[Olive] LOVED Twirl DressThey have a BUILT IN pettiskirt! Layers of tulle + lace give this dress amazing "poof" <3 All sizes have the same amount of layers. The fullness look varies between sizes + colors (and a lot of it is the angle of the picture). Tie back waistband to give it the perfect fitted look. Perfect for all climates (wear alone or they are adorable pairs with our lace layering tops, ruffle cardis or jean jackets)! SIZING In general the dresses fit true to size.
