Among the many celebrity guests at Justin Bieber and Hailey Baldwin’s South Carolina wedding on Monday?

Kylie and Kendall Jenner, who showed up in a pair of skin-baring, super sexy dresses.

The Kylie Cosmetics founder, 22, went for maximum glitz and glam in a crinkled gold asymmetrical gown with cleavage-framing cutouts and a hip-high slit, which she styled with matching gilded Stuart Weitzman “Merinda” sandals($395) and acrystal-encrusted butterfly purse by Judith Leiber Couture worth $5,195.

Her 23-year-old supermodel sister, meanwhile, threw it back to the ’90s in a green crushed velvet slip dress with spaghetti straps and a corsetedbodice, finishing the look with crimped, center-parted hair for added throwback effect. Like Kylie, Kendall accessorized with a sparkly bag; hers was an Alexander Wang rhinestone chain-mesh pouch($695).

Also in attendance atthe Montage Palmetto Bluffwas Baldwin’s palJustine Skye, who sported a sultry one-shouldered black satin dress forthe occasion.
