I'm 5'3", 172 lbs, hourglass figure, (42" bust, 36" waist, 47" hips) Ordered a size 16W and it fits perfectly. However, I had to cut it down about 20cm as it's too long and I'm too short, but I will be wearing it to my brother's wedding this April. It looks absolutely stunning...no need to wear a bra, and will probably use sticky pads to pull my breasts up. I'm 100% satisfied. Now, it's more expensive than other dresses, but I know exactly why. It's heavier than you think, keep that in mind. Very pretty.
