16 Affordable Evening Dresses to Wear to Winter Weddings

Maybe your fanciest friend is tying the knot next month, or maybe you have a charity gala coming up—either way, an affordable evening dress is the best way to ensure you don't blow your budget before the holidays while still keeping you appropriately dressed for the occasion.

Naturally, fast-fashion retailers are going to be the first place to look for under-$150 (and even under-$50) finds: Zara's Jackie O–style minidress with a sheer overlay is a steal at $40, while COS has an artsy cocoon number on sale for $68. Wrap-front styles—from Eloquii's shimmering Lurex dress to ASOS's draped gown—are flattering on a wide range of figures, and simple slips are a smart bet (not least because you can dress them down with a moto jacket long after the black-tie party is over).
