Founded in the late nineties, you can always rely on Theory when seeking a pared-back piece that you'll wear for decades. The latest example? This dress mini dress, which is plucked from the New York label's latest collection. Woven from a lightweight blend into an A-line silhouette, the sleeveless style is defined by its square neckline, which we reckon is primed for showing off your favourite necklace. Slip it on for big days out in Manhattan, we say.
