Fits wells!

I love this top. I wish I can keep it, but it's too trendy to buy (which is why I rent). There are three ties in the front. It does feel very secure. The fabric is nice and light. Not at all scratchy. I wore it on a 85 degrees day. Highly recommend!

loved

a bit snug in the underarms, but a bigger size would have been too big. Very cute, lightweight, perfect for summer top!
