Intimates Are Uniquely Hard to Sell Online
Lingerie, bras, and shapewear face estimated return rates of 30–35% online — among the toughest categories in fashion. The reason is simple: few products demand a more precise, more personal fit, and few are harder to judge from a photo. A bra that's one band or cup off isn't "close enough" — it's a return.
Reason 1 — Fit Tolerance Is Almost Zero
Like swimwear, intimates have to fit exactly to be comfortable and to work as intended. There's no layering to hide a near-miss, and the difference between the right and wrong size is small but decisive. That makes the size decision high-stakes and unforgiving.
Reason 2 — Sister-Size Confusion and Sizing Myths
Bra sizing is full of long-standing misconceptions. Many shoppers stick to the size they think is right, overlook sister sizes that might fit better, and assume every brand fits the same — even though sizing varies widely. Globally, fit and sizing issues drive over half of apparel returns (53% per Prime AI, up to 70% per McKinsey), and intimates sit at the hard end of that range.
Reason 3 — Bracketing and Guesswork
Because fit is so hard to judge online, shoppers hedge by ordering multiple sizes — inflating returns by design, especially where returns are free.
What Actually Reduces Lingerie Returns
The most effective lever is giving shoppers a confident, personalized answer instead of a chart to interpret. The data is striking: in one study, when shoppers picked bras from a general listing, 20% returned their purchase — but when they followed a direct product recommendation, only 5% returned. A 4x improvement, from the same catalog, just by replacing guesswork with guidance.
Other proven moves:
- Detailed measurement guides and clear fit notes.
- Surfacing review signals ("runs small," "true to size").
- Fit guarantees and easy exchanges to build confidence.

Where YourSizer Fits
Intimates are exactly the category where a precise recommendation beats a static chart, because the cost of a wrong guess is so high. YourSizer turns "here are the measurements" into "here is your size" for each shopper and product — the lever most directly tied to fewer returns. See how it works on the for-brands page.
