I try to be as detailed as possible in my reviews to help others. I went based on the reviews and I went a size down and ordered a small. I should've ordered my regular size (medium). I am 5'5 around 150 pounds. The dress fits but would have been more flattering in my right size. The zipper does not lay flat it bunches. It definitely hugs the curves. I need lose weight anyway so I will keep it! The quality is phenomenal. It is warm and a thick material. Will order other colors in my proper size.
