Skirting up for work in the sticky August heat is not exactly high on our list of favorite fashion activities. The city is deserted, coworkers are constantly rotating through vacations, our go-to shopping sites are tempting us with warm and fuzzy (and infinitely more layerable) fall looks—let’s just say we’re not fired up to create new office-appropriate ensembles. What we can do, though, is invest in one or two more sleeveless shells to last us till September. Right now, they’ll keep us cool in the sticky Washington summer, and when the temps drop, they’ll look just as cute under new jackets and cardis. Here, a roundup of 15 solid (and some seriously affordable) options from some of our favorite stores.
