I wear a US medium shirt usually and I ordered an XL, following other reviewers suggestions. It was too snug across the chest and collar, I would say it was like a US small. And there was a small tear in the back by the shoulder, so I returned it. I ordered an XXL thinking it would be just right, but I got it today and it is WAY too big! So I'm ordering another XL hoping that the first one I got was incorrectly manufactured.

The other thing to note is a sleeve length is too short. They aren't really three quarter length sleeves and they certainly aren't full length sleeves. It came about an inch and a half above my wrist, it just looked weird. (I'm only 5' 3") So, I rolled the sleeve cuff and it was cute. I'm guessing the sleeves were designed for little tiny Asian women as well.

Other than the sizing issues, the shirt as well made and really cute. I love the color. It will work perfectly for my pirate costume, if I can get one that fits! 3rd times a charm?
