Here's a long sleeve long formal prom dress that is a modern style with a vintage vibe. The long sleeve prom dress has a sheer-lace bodice with a beautifully scalloped v-neckline and sheer lace sleeves that end in matching scalloped cuffs. In misses and plus sizes, this gorgeous evening gown has a deep v-back that tops the curve-hugging long skirt as it pools into a follow-me train for a look of drama. Surprisingly priced below $200 for prom, fancy galas, and other black-tie formals, this long sleeve long formal prom dress is a classic design with a modern-day twist.
