This pic convinces me that a jumpsuit is 100% essential this fall (and perhaps forever)! The all-in-one outfit is easy-comfy cool, and this iteration by One Teaspoon is especially amazing, with its sleek and flattering fit. Also incredibly chic: Schutz's thong sandals that will really truly go with everything! More one-and-done wonders worth considering are by The Frankie Shop (a cult hit in NYC!), Alex Mill, Rebecca Taylor, and Madewell.
