I would have preferred a 10 for my torso and butt, but the 10 smushed my boobs so I went with the 12. It was more comfortable but still very flattering. I didn't need a bra (shockingly) and still felt supported. I was able to dance and sit for dinner comfortably. Overall I'd totally recommend this dress for any size, and know that it def looks great for full busted ladies! Thank you RTR! Also, I didn’t pick this out on my own, Stylist Jessica at the RTR Varick St showroom picked it out and it was a winner!
