I bought this dress in small and medium because I really liked the color and style and I was not sure if the small would fit. I am 5'4 145 pounds and the small fit perfect. The dress is very comfortable and soft. Just in case you don't realize it there is a zipper on the back of the dress. The only reason i am mentioning that is because the first time i tried it on I did not know it was there till the second time I went to actually wear it and noticed it. The zipper was a little hard to zip up so I had my husband do it and he had little issues. So if your able just to slip into it with out unzipping I would try to go that route. I don't regret now having 2 of the same dresses in the different sizes.
