Great quality but runs a little big

Went up a size

I am keeping this dress. I love the thick material. I love the fit. Size small. I am 5'6 and 134lbs. There is a side zipper. At first I did even realize it was there. I was able to slip this dress over my head without unzipping it.
I purchased multiple dresses for my trip.....im not wearing this on for the trip but definitely keeping this dress. Especially at this price.

Dress is really comfortable. Nice material. Ordered next size up and fits great.
