Really love this dress! Material is good and not see through. I lucked out and got good floral placement throughout the dress. I'm 5'4" and about 112lbs and 32D. I ordered the XS/S and it fits great, just a little snug in the waist.
I'm 5'3 and 110 lbs and I got a s/m and it fit perfectly. I had to pull the straps on the back tighter but that wasn't an issue. Just long enough to feel comfortable wearing it out and about on a windy day but still short enough to be flirty. No way to wear a bra with it though because of the open back, and a tiny bit of side boob is visible depending on your bust size. Definitely worth the buy ☀️
