Why we're often the ones telling apparel brands not to move
If you make apparel, you've probably built up real operational competence on Amazon's self-service marketplace (called 3P — third-party — where you list and sell your own products directly through Seller Central, often using Amazon's fulfillment service FBA). And that competence is hard to replicate on the wholesale-to-Amazon channel (called 1P — first-party — where we sell your product to Amazon wholesale and Amazon resells it). For most apparel, switching from 3P to 1P would subtract more value than it adds.
The reasons are structural to your category:
Size variation: Every SKU has 5–10+ size variants. On 1P, each variant becomes its own line item in Amazon's vendor catalog and forecasting system. On 3P, you manage them more flexibly through your own inventory tools.
Return rates: Apparel return rates are 2–3× what you'd see in other categories. FBA's return-handling infrastructure (inspecting, repackaging, returning to inventory) is built around this reality and actually serves apparel well. 1P doesn't have an equivalent — returns become a vendor-side problem.
Lifecycle iteration: New collections, seasonal launches, color drops, capsule lines — apparel runs constantly. 1P's 30–60 day setup cadence per SKU isn't built for that pace.
Pricing and promotional control: Apparel runs aggressive promotional cycles, markdowns, BOGO offers, end-of-season clearance. On 3P you control all of that directly. On 1P, Amazon controls pricing decisions on your products once you've sold them in.
The narrow situations where 1P does fit
Some specific situations within an apparel catalog do fit the 1P channel cleanly:
Non-size-varying accessories. One-size-fits-most hats, scarves, jewelry, belts in standard sizes, wallets, basic bags. These avoid the size-variation problem entirely. Selective setup on the bestseller accessories.
Established performance / functional apparel with stable demand. The bestseller base layer that hasn't changed materially in three seasons. The multi-year-stable activewear staple. These have stabilized enough that 1P's slower iteration cadence stops being a problem. Selective on the stabilized SKUs only.
Professional / workwear / uniform apparel with B2B-pack relevance. If you make workwear, scrubs, uniforms, or professional apparel, companies sourcing for their workplace through Amazon Business (Amazon's B2B side — the version of Amazon companies use to source for their workplaces) are a real buyer flow. Bulk and case-pack workwear surfaces to those buyers through 1P-channel Amazon Business pricing.
Premium / luxury apparel with chronic unauthorized resellers. If you're a premium brand dealing with parallel-import sellers and gray-market listings, becoming Amazon's only authorized seller (called 1P consolidation) can shut that pattern down — same mechanic that works in household and pet hero products. Full Channel setup, less commonly used but real when the brand-protection need is strong.
The rest of your apparel catalog
Should stay on 3P. The category dynamics reward 3P's operational flexibility, and apparel brands that already run good Seller Central operations are usually best off keeping that competence sharp.
