i'm 5' 2 1/2" 100 lbs. i rented the 2r and it was a size too small. the dress is gorgeous, and i could've gotten away with it a bit tight; but it was also way too long and arrived in poor condition. i assume rent the runway will fix that and not send it out again looking like it'd had a rough night. still, as other reviewers mentioned, the front piece hangs lower than the rest of the dress. and it is small. i'm usually a 0; so i was surprised that the 2 was such a tight fit.
