Definitely runs about a size smaller.I wore this for a superbowl party. It's for kids so I got a large. I'm a small. It fit well just short but they aren't meant for adults. It did its job. Its light and soft.Ok quality. It's for a Halloween costume so not a big deal. Runs VERY small. This is an XL(16) on my 9 yr old daughter. She usually wears a medium.Great, just cut small.Look great too small did not represent the sizeShirt is short. Arrived almost an entire week late.I bought this for a school dress up day and it worked perfectly but wasn't as large as I had hoped. I ordered a few sizes up hoping to get more wear out of it. At least we can hand it down to my 2yo...This is meant to be for a teen with no boobs.
