Tropical Patio Dress

I really like the look of these long dresses, but I really need to hit a few stores and try a couple of different styles on because although they always look so fresh and chic on others, I worry that would be a disaster on me. This version at Banana Republic looks like a keeper though. Tons of design considerations that are typically flattering like the sweetheart neckline and empire waist. And the skirt is pretty basic (no layers or ruffles), so it shouldn't add even more mass to a gal's silhouette.
