I would my small size and medium size. I have the medium size when i taken and the small size he gave me.Thank you!!!I tend to be quite particular when it comes to clothing fit and quality, and I must say, this dress was well worth the splurge in both categories! I recommend sizing up if you want to avoid a skin tight fit; I’m typically a dress size 12 at 5’10” 185 lb, and found that the XXL fit me best. I ordered two different sizes to trial, then returned the one that didn’t work (YAY for Prime).Contemplate no longer, buy this dress!So although I liked the dress, I ended up sending it back. The color isn’t what many would consider bone, but I wanted something grayish anyway, so that wasn’t the problem. The problem was that it fits smaller than it should according to the sizing chart measurements. It was too tight and showed every detail underneath, which I didn’t feel looked good. I may try going a size up....we’ll see.Dress has a heavy overlay! Returned as it was uncomfortableSnug and the material was heavy and scratchy. The attached slip hangs out from underneath the dress. Quality simply doesn’t match the price.This Dress was a hit. I received a lot of compliments. It was the perfect fit. The only drawback is my hair kept getting caught in the sequins and by the end of the night I had strings hanging from where I had to untangle my hair off of the dress. Other than that it was all around perfect.I LOVED the dress. I am post baby, so I am still getting used to my current size and should have ordered a size larger but with that being said it still fit beautifully with it being stretchy. Don’t hesitate to buy.This dress is so gorgeous but the sleeves were too long and it's cut kinda big for a Large (12) so I wore for probably an hour. I wear a 38dd as well and wore a strapless bra I had to pin to my dress due to it being half backless and I also have small hips so it may stretch out on a wider hip... Its a bit kinda heavy too..I got soooo many compliments and i like to be XTRA bcos its Scorpio season duh..LOLGet it hunny.I am 5’ 7” athletic build and 32C and 140lbs. I ordered a size small and the dress fits perfectly. This dress is worth every cent! It is elegant. it is important to note, the bras with straps that I own show at the back (not much but they do show). I read other reviews on here that the straps don’t show so maybe yours won’t either! I do have a strapless bra and the band does not show. The dress also has some weight to it just an FYI. The zipper is well built in with a sturdy butterfly clip. The nude lining is shorter than the fabric with with sequence on me as well. This a very well made dress. I plan on getting other colours when special events presents themselves. Hope this helps!Very disappointed the colour is very different in person the sequins where not all flat some where bent and worse of all the slip was longer than the dress!Love my dress they are amazing. Took care of my exchange super fast.Fits perfect very well made
