Corsets are the category with the highest return rate in many boutiques — not because customers don't love them, but because the sizing was wrong before the order was placed. As a manufacturer that ships steel-boned corsets to retailers worldwide, we see the same mistake repeated: buying a single size run and hoping it fits everyone. Here is how to buy corsets wholesale so your customers keep them.

Understand the three sizing systems

Before ordering, know which system the factory uses, because corsets are not like t-shirts:

  • Bust-based sizing (S/M/L): the most common for fashion corsets and bustiers; easy for customers but less precise for steel-boned pieces.
  • Waist-based sizing (inches): the classic corset system — the size refers to the waist measurement the corset is cut for. This is the standard for steel-boned corsets.
  • Plus-size runs: extended sizes (up to 4XL/5XL) that follow true-to-size garment measurements rather than scaled-up S/M/L.

Ask your supplier for a size chart with actual garment measurements — waist, underbust, bust and length — for every size. If they cannot produce one, buy elsewhere.

Know what "steel-boned" actually means

Real steel-boned corsets use flat steel springs (or spiral steel) in vertical channels, not plastic. Plastic bones bend out of shape after a few wears and ruin the silhouette. When you inspect a sample, bend the channel between your fingers: steel springs back, plastic doesn't. Our ribbon-tie fishbone camisole and burgundy lace fishbone camisole are examples of bone-structured pieces that keep their shape.

Buy for your market's body type

A size chart from a Chinese factory is cut for Asian body proportions by default unless specified otherwise. If your customers are predominantly in the US, UK or Australia, order graded size runs with fuller bust and hip allowance, and ask the factory to confirm the grading. At Glory we produce plus-size runs (up to 5XL) on the same lines — see our plus-size bustier corset — precisely because most Western boutiques need them.

Stock the right size mix

For corsets, M and L outsell S by roughly 3:1 in most Western markets, and extended sizes (XL–3XL) account for a growing share of revenue. A safe opening order per style: S 10%, M 35%, L 35%, XL 15%, XXL 5%. Adjust after your first two months of sales data.

Build a returns-proof product page

Returns start at the product page. Every corset listing should show: the size chart in both letters and inches, the underbust-to-hip measurements, how the lacing adjusts fit, and a photo of the back lacing system. Link your listing to a fit guide — ours at the Guide shows customers how to measure themselves correctly.

Frequently asked questions

What is the difference between a corset and a bustier?

A corset extends below the waist and typically uses steel bones for waist shaping. A bustier is shorter, bra-like in function and usually has lighter boning. Fashion corset tops sit between the two — structured but not waist-training.

Do steel-boned corsets stretch?

Steel bones do not stretch — that is their purpose. The lacing at the back is the adjustment mechanism: a properly laced corset can fit a range of sizes, which is why waist-based sizing works best.

What MOQ applies to corsets?

For stock styles at Glory, corsets start at 1–5 pieces per style so you can build a size run affordably. Custom fabrics and colors have separate MOQs.

How should customers wash corsets?

Hand wash cold, never machine wash or wring, and dry flat. Steel bones will rust if left wet. Include this care note in your packaging to cut returns.
