Many people are hesitant to order online because of fit. Will it be too tight? Too loose? Too short? Or too long? Will it be the right cut for my body type? Is it supposed to fit like this? To help ease the uncertainty, we've put together a comprehensive fit guide. It will walk you through the various steps to finding the right UA fit for all our gear so you can order with confidence.

Most Under Armour® gear is designed to fit close to the body for zero distractions, but is still consistent with traditional sizing parameters. This means if you normally wear a "Large" T-shirt, you would also wear a "Large" UA T-shirt.

How To Measure

BAND SIZE: Standing straight up with an unpadded bra on, measure closely around the chest just under your arms, right above the bust. If your result is a fraction, round to the nearest whole number. (ex. 33.7" rounded to the nearest whole number, your band measurement is 34")

CUP SIZE: While wearing a non-padded bra, keep the tape parallel & measure at the fullest part of your bust. Round this measurement UP the nearest WHOLE number. Subtract BAND size from BUST size to find your CUP size. EX. 36" - 34" = 2" = B = 34B
