I have a long torso and wider back/thick middle in proportion to my narrow tights.  i was worried after reading other reviewers comments.  for reference i'm a 2 in pants, 26-27 in jeans, xs in retailer tops but for floreat and maeve i'm always a 6.  i ordered a size 6 and it was perfect.  with my long torso i expected this dress to fit weird but it was perfection.  in love.  i wore it with faryl robin lace up sandals
