Finding your perfect fit shouldn’t feel like a guessing game. At Thread Theory, we’re here to make it simple—so you can shop with confidence.

First, grab a measuring tape and check your bust, waist, and hips. No need to pull it tight—just measure naturally for the best result.

Next, think about your style. If you like a closer, more tailored feel, go with slim. Want something more relaxed? Then relaxed fit is your best bet. We call it out clearly on each product page, so you’ll know what you’re getting.

As a general guide, if you are between five foot two and five foot six, we suggest a small. Between five foot seven and five foot eleven, a medium usually works best. And for those between six foot and six foot four, a large should do the trick.

Still not sure? No problem. Our stylists are just a message away. Or take a look at the reviews—real customers often share how each piece fits them.

No guesswork, no hassle—just clothes that fit you right. Happy shopping!
