Hailey Baldwin's Sexy '80s Ballgown Comes With the Most Unexpected Cutout

Hailey Baldwin knows how to serve up a gala look. After walking the Met Gala red carpet at the start of the week in a scandalous, pink Alexander Wang gown that featured a daring accent on her back, the supermodel rocked another ballgown. Hailey attended the Endometriosis Foundation of America's 10th annual Blossom Ball, which took place at Cipriani Wall Street in New York City. She posed for pictures with her sister, Alaia, who also dressed to the nines.

Hailey opted for a black velvet ballgown from Giambattista Valli. Her strapless gown was covered all over with little crystal embellishments; the crystals coupled with the velvet material reminded us of '80s glam. When she posed to the side, we saw that her gown actually had an unexpected cutout on one side right under her chest. The sliver of skin was covered up by a sheer beige panel and a big bow above it. She completed her outfit with drop earrings, a diamond-encrusted watch, and Jimmy Choo heels. Alaia wore a snakeskin-print one-shouldered gown with gold glittery heels.
