Is COS true to size?
COS's real size chart is below — the body measurements each size is cut for. There's no universal answer to “what size am I”; it depends on your build. Paste the COS piece you're eyeing and CHECK puts it on your own photo with a size built from your measurements.
Two numbers and your fit taste, read off COS's real chart. Free, no account. Try it on your photo after.

Body measurements (cm) each size is drafted for. CHECK reads these against your build to land your letter.
COS sizing — common questions
Is COS true to size?
COS fit varies by piece rather than following one rule — the per-piece notes below are the honest read. The only honest answer for your body is a size built from your measurements against COS's real chart — that's what CHECK does, free.
Does COS run small or large?
It depends on the piece — COS doesn't follow a single rule. Check the specific garment's fit notes, or build your size on your own measurements to be sure.
What size am I in COS?
There's no universal answer — it depends on your height, weight and how you like things to fit. CHECK reads COS's real size chart and builds a recommended size from your measurements in a few seconds, then shows the piece on your own photo. No account needed for the first few each month.
Do COS tops fit true to size?
COS tops are covered in the fit notes above, piece by piece. Where we have the brand's chart, CHECK pins an actual letter to your build; where we don't yet, you'll get a directional read and we'll say so plainly.
How can I see how COS looks on me before buying?
Open any COS piece on CHECK, drop in one photo of yourself, and we'll show it on your body — an honest visualization, not a model. You also get a size built from your measurements. Try it at checklook.me/sizing/cos.
