I am a medium in American clothing normally (size 8, 5'8.5"/174 cm) but I have big boobs and a ****, so I was a little worried about the width. It fit perfectly and is designed like those t-shirts that curve inward a little to flatter your curves. If you are looking for a regular t-shirt look, get it in the mens version, but if you want to accentuate your curves, get it in the womens.
