So many ways to style it and fits perfect! I always worry about the straps and length as I am very short and dresses tend to be too long or the top part hangs low on the chest but not with this dress! Only thing I wish is that the material was a little thicker. It’s very thin but helps it be a little flowy,” writes a reviewer.Shop HalifeHalife Casual Spaghetti Strap Midi Dress with Pockets, $, available at AmazonMitilly Loose Swing Casual DressWhile most of the dresses in this roundup boast a rather traditional construction, this fluttery mini dress has some unexpected details, like an asymmetrical drop empire waist, three-quarter sleeves, and the all-over ruffle hems. Unique? We’d sure say so. “I don’t usually bother writing reviews, but for this dress I had to!! I needed something feminine and youthful and fresh looking AND something that would make me look SLIMMER! JACKPOT!!” writes one enthused wearer. “I’m curvy and this dress drapes – PERFECTLY.
