I'm usually a 6 in dresses and the 6 here fit okay. loose but still flattering a little long for a sundress. i was unhappy with it looking a little frumpy and being so loose under the arms all my bras showed . i took it back to the store and after reading the reviews here decided to try the smaller sizes...well multiple dresses later i ended up buying a size 2 petite!!! and i'm 5'9". the 2 reg and petite still had the loose gathering look to the top but both fit much better under the arms so tha
