Product Details

The little black jumpsuit. The Onyx Wide-Leg Jumpsuit is the LBD's cooler cousin — a sleeveless one-piece with a subtle sheen, a waist-defining belt, and wide legs that flow like evening trousers.

It's cocktail-hour ready straight off the hanger, and sized from XXS to L so more shoppers find their fit. Heels make it formal; flat sandals make it a rooftop dinner. Either way, it works.

Elegant sleeveless cut with a subtle shine finish
Included belt for a defined, sculpted waist
Wide-leg silhouette that flows and flatters
Extended sizing from XXS to L

Free USA shipping over $50 · 30-day easy returns · Limited run — when your size is gone, it's gone.
