I'm 5'4 and 160 lbs, normally wear a size 10. I ordered a 12, which zipped but was definitely on the tighter side. The material isn't stretchy at all and this runs a bit small in general. The bigger issue for me was that this is intended for someone with a smaller chest. As a DD, the side without a strap left me very exposed - there just isn't enough material extending past the waist section. Would probably fit well on a single D or smaller.I loved this dress! The quality is amazing for the price. I bought a size 8 but it was slightly large in the bust and about 5 inches too long. I'm 5'8" and 130lbs. I exchanged it for the size 6 which fit like a glove! It's also longer but only about 2-3 inches which doesn't bother me at all. I would 100% buy this dress again.They also handled the exchange quickly and I got the new dress in less than 1 week, 2 days before it was supposed to arrive!!!Could not be happier with my purchase.This dress is perfect for many occasions. The material and shape of dress is very flattering. I am 115 pounds and 5' 4 and ordered a size 2.. I found the part where my ribs are to be a little bit tight and the dress was a little long for me but otherwise perfect. It comes with minimal padding which is nice because you really do not have to wear any sort of bra with the dress. Overall great dress and would highly recommend it.Beautiful dress. Runs small and couldn't zip even though the measurements said it should fit.Zipper is hard to close without help, otherwise it was the perfect bridesmaids dressThe dress was very pretty but a little snug!too large in the chest and too long. Not as nice as I expectedBeautiful dress but it's to bigPin tucks didn’t work with the fit.
