I’m not one to shy away from showing a little skin, but my older, wiser self realizes that midriffs works best by the beach. I feel that I’ve matured beyond belly flashing to more appropriate show-and-tell, like the shoulder (see Show a Little Shoulder) and the back. But backless gowns can sometimes be too dressy, which is why I love this organic cotton Rondinara dress by Machja. The understated back cutout and serigraph print give it that little bit of edge without making you look socially clueless while you're just going out for groceries. The cap sleeves and basic shape keep it subtly sexy, just how I like it. ($85.)
