The sizing is off, it's definitely on a small side (and I'm standard S usually, with narrow hips and 34B-34C size and could hardly zip up the jacket). The quality is exceptional though. Opt for a size up if your top is somewhat larger than the frame.

It's a bit big for a small, but there was no extra small so it'll work. I'm sure it'll shrink a bit once washed though.

It's getting cold and my 10 lb. Toy Poodle needs a little sweater for our walks.  However, I bought this in a size M, but it's too small.  I tried it on her with some difficulty, but taking it off was even worse.  I thought I was going to have to cut her out of it.  I may try buying it in a large and give this one to my sister who has a 5 lb. Chichauhau, if I don't return it.

looks nice, but waaaay to small!!! If the sizing was more accurate I would have given 4 maybe 5 stars.

I bought a small but I would think this is closer to a medium, it's not designed to be worn without tying the string, so it's a bit of a hassle.

I wish I had ordered a full size down from this. My son is starting to wear Size 5 shirts, so we had originally ordered a Size 5, which was nothing short of enormous. We traded it in for a Size 4, which is typically too short in length and sleeves for him, and we ended up having to ROLL THE SLEEVES they were so long! Even after washing. It's a great shirt, but the sizing is definitely off. If you order a size down, it should work fine.

On my flag stand this is tiny. The sizing is off. Not quite worth the money.

It's just too small and definitely surprised me. If I knew it were so small, I would not buy it.

Workmanship is great, resembles the photo exactly. Sizing is definitely not accurate. One size fits all maybe for youth, but not adults. I wear a size 7 1/2 hat, and never had an issue with one size fits all. This is terribly tiny. With the price I spent, and the quality, I am ok, but the size is way off and I am disappointed with it. This hat will go to my 10 year old, but I fear it may be snug on him as well.

This is not an extra large size, more of a large and is tight.

Sizing is way off. I ordered teh XL and my daughter who is a size 0 - 2 could barely get in it. So needless to say my size 12 was not. It is a very cute top and is well made for what you pay, just be aware that sizing is way off.

This IS very cute, however the 3X fits a medium in American sizes (not even a large sized person could wear this comfortably for a cover-up.) It doesn't just run small, it runs VERY SMALL. If there had been ANY indication that this is an Asian made product I would have know better than to order it as their tiny sizes are always way off. I'm returning it, even at under $10.

The style is cute, but dress sizing is way off. This runs really small. I normally wear an extra large and I could not even get my arm into this size 2X. Quality is not great, but it was inexpensive. I would have been happy to wear it for a wedding I had to attend, except it arrived way too late...then was way too small. I knew it was coming from China so I didn't expect it to be here too quickly, but it did take several weeks.

The size is so small and feels so tight, It's very different from my thought

I measured to make sure sizing would be alright. It is sooooo small I can't even wear it. Based on they're suggested measurements I ordered the size they said would work. We are talking maybe 5 sizes off. Horrible. Which is a shame because its cute.

The fit is off on this, somehow; it's much too large and I thought I could shrink it, but can't. I'm not very small, but I needed a small, apparently (I'm 5'5" and weigh 140).
