Wrap Dresses Wrap dresses, which form V-necklines, work well for the inverted triangle figure type. Avoid puffed sleeves and ruffles on a wrap dress so that the top won't look larger.
Sheath Dresses with Pegged Skirts A well-fitting sheath dress with a pegged skirt to make hips appear a bit more in balance with broad shoulders is another workable style for the petite woman who has an inverted triangle shaped figure.
Dresses with Hip Detail Dresses with hip detail, such as a ruffle or pockets, also put more emphasis on hips and help balance the shape of an inverted triangle figure so that it looks more like an hourglass.
The white silk dress pictured above from Fernanda Carneiro Designs (Vendor's Site) features a flattering V-neckline, sheath styling, and ruffle at hip, all style details that flatter a woman with an inverted triangle shaped figure.
