I bought this dress in store. It was very comfortable and I got a lot of compliments. I bought this dress because I was 5 months pregnant a month in advance so it would still fit on Halloween. I also know costumes sell out in my size pretty early. I'm very petit for my age and 5'2. It wasn't too long either. My only concern was that when I tried it on in store (which I'd recommend) was one of the side ties to tie the dress in the back was almost completely off. I didn't really needed it anyway. But the employees were very nice and helpful, and due to the missing tie they gave me 15% off the dress because it was the last one in my size. The arm bands are sequined elastic which I'm assuming is so that it would fit woman of all sizes.
