I am a size 12 and ordered the XL. This would fit a doll. It is the tiniest dress I've ever ordered. I gave it to my friends 10 year old daughter for dress up.

These are a perfect size 12 US

The problem is, I am size 11 and requested a size 11.

I am a size 12. They do fit but are tight and take some time to get on. Other than that these are a great item and I enjoy wearing them.

I ordered XL, because I wear size 13. They're probably a size 11.... but they still barely fit, and they're warm, so they're doing their job well!

I was afraid the XL was going to be too big. It's not. I'm a size 10 and it is not big

I normally wear size 11 and ordered the 12 and they are still a little too tight. They are quite narrow. Hopefully they will stretch out some.

I ordered an XL knowing that it would fit tight (which I wanted), but it was SO, SO small.  Just order bigger than you need.

I always wear a 12, so that's what I ordered.  They were too small, so I'm returning them for size 13.  Luckily they have free returns.

I'm a size 12 and bought an XL and it's almost too small. It will work for spin class but I doubt I'll wear it out in real life.

Fits as expected for a size ten...I ordered this size ...I am a size 12-14 so that size sounds big for me but they fit just right ..not baggy.
I do not have a big derrire either. So I'd say they are running small...I just knew the size to order.

Looks okay, but I ordered XL after reading other reviews (I wear M), and it is definitely an XL. I think they have their sizing right now

Reviews said they ran small so I got XL instead of the L i would have gotten being size 12 and they are perfect.

I ORDERED AN XL WHICH WHEN I CHECKED THE SIZING CHART WAS WHAT I SHOULD HAVE ORDERED.  THE SHIRT SAYS IT IS AN XL BUT IT IS ABOUT FIVE SIZES TOO SMALL.

I ordered an xl, too small for me but my friend who is a medium was able to wear it. Sizing is not accurate!

It came on time as expected but size was small for me Xl is in no way for a size 12.
