Your fit, before you commit.
Seamli AI maps your body proportions, simulates how garments fit, and gives you a clear fit score before you buy. No more bracketing sizes or hoping the tailor can fix it later.
Sizing is broken in online fashion.
Every brand fits differently. Shoppers order multiple sizes, return up to 40% of orders, and still never know how a garment will sit on their body until it arrives.

of online fashion orders returned, often due to fit

About Seamli AI
Built from lived frustration
Our co-founder altered almost every piece she bought. As a petite, curvy shopper, nothing sat right off the rack.
She ordered multiple sizes every time and returned most of them. Pieces still sit in wardrobes waiting for alterations most of us never have time for.
For too long, shopping meant compromise: buy, then alter, or settle for close enough. For many people the issue is proportion, not just size.
Seamli AI shows how clothes fit your body before you purchase. Great style should not require guesswork or a trip to the tailor.
Shop with confidence. Sell with confidence.
