I’m 5’4” and 138 lbs and a Small fit me, but I’m small in the chest area, so it worked. If I was bigger than an A/B it probably would have been too tight on me. I love it and only wish the girls dresses hadn’t sold out because I really wanted my girls to match me but there were none left when I went to order.
This dress just did not fit right. I ordered up from my normal size, and felt like there still was not nearly enough room in the chest, but the smocking on the back looked very baggy. Ended up returning because it just was not wearable on my body.
I wear a medium for most dresses and it fits just right. It looks cute on and ready for spring. I hang my clothes to dry and I use steam to iron it out as needed, so haven’t tested it in the dryer for any shrinkage.
