This dress is absolutely stunning and very flattering. I originally purchased this dress to wear as my second dress on my wedding night, but the only reason I chose to wear something else was because it resembled my long wedding dress too much. Never worn. Also is flexible in size up to an 8 or down to a 4. The corset means you can tighten and it’s very easy to get tailored. It’s a US 6. Does not come with box. It does come with the original undergarments with the protective sticker on. I am 5’5. When I first bought the dress, I weighed 122 pounds. I now weigh 135 in the pictures you see above. Because of the corset and the straps, it can still fit.
