Based on reviewers' comments, i sized up and ordered an 8 (normally i run 4-6). and while the waist fit pretty well, the bust was too large and roomy (i'm a34b bust). i eventually got ahold of a 6 and the waist still fits and the bust is much better. so for me, at least the two dresses i got are true to fit. and the dress is very pretty and i'm excited to wear it!!!....i guess since it's fall i may have to wait until next year...
