I really like the look of this dress. Everything about it is very adjustable, so it's easy to get a good fit. It's very sexy, being backless and having such a deep v in the front.
I'm only giving three stars because this dress is EXTREMELY sheer. Like, straight-up see-through. When I first got it, I tried it on without any underwear and you could see nips and everything downstairs. No exaggerating, you could see my whole butt. There's no lining of any sort and the material is very thin. I would never wear this dress by itself out of the house.
I found a half-slip to wear under the skirt part of the dress. I still have to wear nude underwear but it makes it wearable. I bought one of the lace-up sticky bras to wear too, and it works pretty well if I safety pin the cups of the dress together so the neckline doesn't plunge so much. Even with pinning the cups together, it's a sexy dress that shows a lot of skin. I'm waiting for a pair of silicone petals to arrive that I could wear with the dress. I'm concerned that they won't do enough to cover me up, or that's they'll be really visible under the fabric, but we'll see in a day or two when they arrive. It'd be nice to have the option not to pin the cups together, but I'll be pretty happy with just the lace-up bra if the petals don't offer enough coverage.
If you're up for the undergarments challenge presented by this dress, it's a very pretty, feminine, sexy sundress. I went through the effort to find appropriate underwear because I loved it the second I tried it on.
I'm busty (34DD/32DDD), and the structure of the bodice gives me good enough support to feel comfortable without a "traditional" bra (which is good, because you obviously can't wear a regular bra with a backless dress). I'm usually size a dress size 8/10, 145lbs, 5'7", and my measurements are 39"-28"-40". I bought a size large, and I'm glad I did because I want the extra coverage in the bodice, and I wouldn't want the dress to be any shorter. There's a fair amount of extra room in the waist, but it's fully adjustable with a drawstring and I don't mind the look of the extra gathering from cinching in the waist.
