You'll be floating down the aisle with this floor-grazing chiffon bridesmaid dress that you can wear 3 different ways. Go for an off-the-shoulder look for something a little trendy that also gives you some arm coverage. Can't be bothered with sleeves? Tuck them under your arms for a flouncy effect that moves with you. For something a tad more modest, raise the sleeves up to your shoulders for a draped v-neck look.
