Gorgeous dress. Very comfortable and free flowing.

Im 5 tall 110. Usually wear a size 2. I purchased a Small and I almost couldn't fit into this dress had I not loose 2 more pounds. The model in the picture is how skinny you need to be to wear a Small. Also, being only 5 tall, I hemmed about 7 on the bottom and adjusted about 1 on the shoulder in order to fit in it perfectly.

So if you are 58 skinny tonthe bone, the Small will fit you perfectly.

Its a very pretty dress, wish I didn't have to do so much to fit into it
