Open-Pack vs. Pre-Pack: The USA Menswear Retailer's Guide to Ordering Tailored Jackets Without Stranding Inventory

Quick Take: The open-pack vs. pre-pack decision is not a preference question — it is a margin question. A USA menswear retailer who defaults to pre-pack ordering for tailored jackets without understanding their actual size run sell-through data will consistently strand inventory in the sizes that the pre-pack over-allocates and sell out of the sizes that the pre-pack under-allocates. A retailer who understands when open-pack ordering protects their margin and when pre-pack ordering makes commercial sense will build a tailored jacket assortment with the right size run depth for their specific customer base — and will generate significantly higher full-price sell-through rates, lower end-of-season markdown rates, and stronger gross margins than a retailer who makes the open-pack vs. pre-pack decision by habit or supplier convenience.

What Is the Difference Between Open-Pack and Pre-Pack Ordering?

Open-pack ordering means the retailer specifies the exact quantity of each size they want to receive for each style — ordering, for example, 3 units of size 38R, 5 units of size 40R, 6 units of size 42R, 4 units of size 44R, and 2 units of size 46R for a single tailored jacket style. The retailer has complete control over the size allocation and receives exactly the quantities they specify in each size.

Pre-pack ordering means the supplier bundles a predetermined assortment of sizes into a fixed pack that the retailer purchases as a unit. A standard menswear tailored jacket pre-pack might contain 1 unit of each size from 38R to 46R — a total of 5 units — or it might contain 2 units of the most popular sizes and 1 unit of the peripheral sizes, depending on the supplier's standard pack configuration. The retailer receives the sizes in the proportions the supplier has predetermined, regardless of whether those proportions match the retailer's actual size run sell-through data.

The commercial stakes of this decision are highest in the tailored jacket category because tailored jackets are the highest-price-point piece in the menswear assortment — typically retailing between $180 and $380 in a USA menswear boutique — and because size run mismatches in tailored jackets generate the deepest markdowns and the highest return rates of any menswear category. A stranded size 38R tailored jacket that a USA boutique retailer cannot sell at full price will be marked down to 40 to 60% of its retail price at end of season, wiping out the gross margin on that unit entirely.

When Does Open-Pack Ordering Protect Margin?

Open-pack ordering protects margin in four specific commercial situations where the retailer's size run data diverges from the supplier's standard pre-pack allocation:

• When your customer base has a non-standard size distribution — A USA menswear boutique in a market with a higher-than-average proportion of larger customers — size 44R, 46R, and 48R — will consistently strand inventory in the smaller sizes that a standard pre-pack over-allocates. A retailer in this market should use open-pack ordering to specify a size allocation that reflects their actual customer size distribution, concentrating the order in the 42R to 46R range and reducing the allocation of sizes 38R and 40R to the minimum needed for the occasional smaller customer.
• When you are testing a new style for the first time — A retailer who is introducing a new tailored jacket style for the first time does not have sell-through data for that specific style and cannot predict with confidence how the size distribution will perform in their market. Open-pack ordering for a new style allows the retailer to place a conservative initial order with a broad size distribution — one or two units per size across the full size run — and then use the sell-through data from the first six weeks of the season to inform a reorder that concentrates on the sizes that are actually selling fastest.
• When the pre-pack allocation does not match your proven size run data — A retailer with three or more seasons of tailored jacket sell-through data for a specific style or category will have clear evidence of which sizes sell at full price and which sizes require markdowns to clear. If the supplier's standard pre-pack over-allocates the sizes that consistently require markdowns in this retailer's market, open-pack ordering is the only method that allows the retailer to apply their sell-through data to the ordering decision rather than accepting the supplier's generic size allocation.
• When you are building a deep run on a proven bestseller — A retailer who is placing a large seasonal order on a proven bestseller with known size run sell-through data should always use open-pack ordering to concentrate the order in the sizes with the highest full-price sell-through rates. A pre-pack order on a large volume will amplify the size allocation error — generating a large overstock in the slow-selling sizes and a stockout in the fast-selling sizes — while an open-pack order concentrates the volume exactly where the sell-through data says it belongs.

When Does Pre-Pack Ordering Make Commercial Sense?

Pre-pack ordering makes commercial sense in four specific situations where the retailer's order size, market knowledge, or supplier relationship makes the pre-pack's convenience and minimum order advantages commercially appropriate:

• When you are a new retailer without size run sell-through data — A retailer who is placing their first or second seasonal wholesale order for tailored jackets does not have the size run sell-through data needed to make an informed open-pack ordering decision. A pre-pack order for a new retailer provides a commercially reasonable starting size distribution that the supplier has calibrated based on broad market sell-through data, and protects the new retailer from the risk of dramatically over-allocating or under-allocating any single size in their first season.
• When the minimum order quantity for open-pack is higher than your volume needs — Many wholesale suppliers set a higher minimum order quantity for open-pack ordering than for pre-pack ordering, because open-pack orders require more supplier-side operational management than pre-pack orders. A USA menswear boutique that wants to order 6 to 8 units of a tailored jacket style may find that the supplier's open-pack minimum is 12 units — more than the retailer needs for a single style. In this case, a pre-pack order at 6 or 8 units may be the only commercially viable ordering method for the retailer's volume level.
• When speed to delivery is the commercial priority — Pre-pack orders typically ship faster than open-pack orders because the supplier can fulfill them from pre-assembled stock rather than picking individual size quantities per the retailer's specification. A retailer who needs a tailored jacket delivery within a tight window — for example, to receive inventory before a major local event or a peak selling period — may accept the pre-pack's size allocation in exchange for the faster delivery timeline.
• When the pre-pack's size distribution matches your customer base — A retailer whose customer size distribution happens to align closely with the supplier's standard pre-pack allocation — for example, a retailer whose customers are concentrated in the 40R to 44R range that most standard pre-packs weight most heavily — can use pre-pack ordering without accepting a meaningful size distribution penalty. This alignment should be confirmed by comparing the retailer's actual size run sell-through data against the supplier's pre-pack allocation before placing a pre-pack order.

How Should Retailers Use Open-Pack and Pre-Pack Together?

The commercially optimal approach to tailored jacket ordering for most USA menswear boutiques is a hybrid strategy that uses pre-pack ordering for initial market testing and open-pack ordering for volume commitments on proven styles. This hybrid approach captures the convenience and low minimum order quantity advantages of pre-pack ordering for new styles while applying the margin protection of open-pack ordering to the styles and sizes where the retailer has clear sell-through data.

• Pre-pack for initial orders on new styles: Place pre-pack orders for new tailored jacket styles in the minimum available pack configuration — typically 1 or 2 units per size across the full run — to test the style in the market without committing to a large size-specific inventory position. Use the sell-through data from the first 4 to 6 weeks to identify the fastest-selling sizes before placing any reorder.
• Open-pack for reorders on proven styles: Place all reorders for proven tailored jacket styles using open-pack ordering, concentrating the reorder volume in the sizes with the highest full-price sell-through rates from the initial order. This approach converts the sell-through data from the pre-pack initial order into a precise size allocation for the reorder that maximizes the proportion of reorder inventory that sells at full price.
• Open-pack for volume commitments at season start: For styles that the retailer has carried for two or more seasons with clear size run sell-through data, place the full seasonal volume commitment using open-pack ordering at the beginning of the season, concentrating the volume in the proven sell-through sizes and minimizing the allocation of sizes with historically high markdown rates.

What Size Run Data Should Retailers Track to Make Better Open-Pack Decisions?

The three data points that most directly inform a better open-pack vs. pre-pack ordering decision for tailored jackets are full-price sell-through rate by size, weeks-to-sell-out by size, and markdown depth by size. A retailer who tracks these three data points for every tailored jacket style across every season will have the evidence base needed to make precise open-pack size allocation decisions that reflect their actual customer size distribution rather than the supplier's generic pre-pack assumption.

• Full-price sell-through rate by size: The proportion of units in each size that sold at the original retail price without a markdown. A size with a 90%+ full-price sell-through rate is a size that the retailer is under-allocating. A size with a sub-50% full-price sell-through rate is a size that the retailer is over-allocating.
• Weeks-to-sell-out by size: The number of weeks from the style's floor date to the sell-out date for each size. A size that sells out in weeks 1 to 3 of the season is a size where the retailer is leaving revenue on the floor by under-allocating. A size that is still in stock at week 10 of a 12-week season is a size that will require a markdown to clear and should be reduced in the next season's open-pack allocation.
• Markdown depth by size: The average discount percentage applied to units of each size that did not sell at full price. A size that consistently requires a 40%+ markdown to clear is a size that is systematically over-allocated in the current ordering strategy and should be cut significantly in the next open-pack order.

Wessi Tailored Jackets Available for Open-Pack and Pre-Pack Ordering

Linen — Striped — Light Blue — 44 Units

Light Blue Striped Linen Gold Button Blazer

The open-pack test candidate. A light blue striped linen gold button slim-fit blazer with 44 units in stock — enough depth to support an open-pack ordering strategy across the full size run for a retailer with proven size run data, or to serve as a multi-pack pre-pack test for a retailer introducing the style for the first time. The linen construction and gold button detail position this blazer at the premium end of the spring and summer tailored jacket market, where the full-price sell-through window is short and precise size allocation is commercially critical.

Linen — Striped — Ecru — 42 Units

Ecru Striped Linen Gold Button Blazer

The neutral colorway companion to the light blue. A retailer who carries both the light blue and ecru striped linen blazers can use pre-pack ordering for the initial market test on both styles in parallel, then use the comparative sell-through data to determine which colorway deserves the open-pack reorder volume. The ecru colorway serves the customer who wants a linen blazer with the broadest trouser coordination range — working equally with navy, grey, and earth tone trousers across the full range of smart casual and business casual spring and summer occasions.

Linen — Striped — Cream — 42 Units

Cream Striped Linen Gold Button Blazer

The third colorway in the striped linen gold button family — cream. A retailer building a three-colorway open-pack order across the light blue, ecru, and cream striped linen blazers can use their size run sell-through data to concentrate the largest size allocations on the colorways with the strongest proven full-price sell-through, while maintaining a minimal pre-pack quantity on the colorway being introduced for the first time. The cream colorway is the most formal of the three — appropriate for weddings, garden parties, and summer formal occasions.

Tailored Suit — Burgundy + Navy — 39 Units

Burgundy Jacket Combined Navy Suit

The combined suit with open-pack size run considerations. A burgundy jacket combined with navy blue suit trousers — a non-traditional formal combination that serves the wedding and special occasion customer who wants color distinction alongside formal structure. Combined suits have a more complex size run dynamic than separates because the jacket and trouser sizes must coordinate — making open-pack ordering especially commercially important for combined styles, where a size mismatch generates two stranded units (jacket and trouser) rather than one. Retailers with combined suit sell-through data should always use open-pack ordering for combined styles.

Tailored Suit — Grey + Black — 31 Units

Grey Jacket Combined Black Suit

The commercial combined suit in the most formally versatile colorway. A grey jacket combined with black suit trousers delivers the formal occasion authority of a black trouser base with the visual distinction of a grey jacket — the right combined suit for business formal, wedding guest, and evening occasion contexts where the customer needs formal structure without the monotony of a solid black ensemble. For retailers new to combined suits, a pre-pack initial order on this style provides the market test data needed to inform an open-pack reorder concentrated in the sizes that proved fastest to sell through at full price.
