I’m 5’8” and 160ish pounds I ordered a large. The length is perfect but a medium would have fit a little better.

I just love this dress, you can fold it up take it on a trip hang it in the bathroom and the wrinkles what little there are ,fall out, I am in my 60\'s, 5\'6 and the length is perfect for me. I usually wear a size XL due to my size 38DD top and it fits perfectly.
