I used to think that Theory made the best sleeveless sheath dresses, but after I bought this dress in turquoise a few years ago, Nicole Miller deserves the accolade. It’s made of thick stretchy linen-viscose-spandex that drapes against the body without too much cling. The front and back tuck and ruching details make it more interesting, and forgiving, than a plain sheath. A great length! Can easily be dressed up or down with the right support act.
