Contact MissySport

MissySport is a small, independent, ad-supported site — there is no support team standing by, but a real person reads what comes in to support@missysport.com.

A few things this address is genuinely useful for: a calculator that gave you a result you think is wrong (say which tool — the sports bra size calculator, legging size calculator, clothing size converter, workout calorie calculator, sweat rate calculator, or the fabric care guide— and what you entered); a tool or fabric you wish were covered on the site; an out-of-date fact or broken link in the blog, learn section, or the museum; or a bug in how a page looks or behaves on your device.

There’s no fixed response time to promise, and no ticket number or live chat — email is read and handled as it comes in. If a question is really about a fit problem, a persistent injury, or a medical condition, a professional fitter or a doctor will have a more authoritative answer than this site can give; MissySport’s tools produce general estimates, not professional fitting or medical/fitness advice, and the site isn’t affiliated with any activewear brand or manufacturer.

Before writing in about a tool result, it can help to double-check the numbers you entered — measurements, weight, or duration are the most common source of a surprising answer. If it still looks wrong after that, that’s exactly the kind of message worth sending.
