Kendall Jenner attended her friend Lauren Perez’s wedding in Miami on Thursday wearing a skin-baring dress with geometric cutouts. On Instagram Stories, the 26-year-old model uploaded photos of herself in a barely-there LBD, posing for mirror selfies with celebrities including Hailey Bieber.

She flaunted her abs in a sultry Mônot style that incorporated small triangular sweeps of fabric across her breast and waist. Kate Hudson, Dua Lipa, and Alessandra Ambrosio have all donned similarly sultry variations on the LBD in recent months, and the reality star is far from the only celebrity using the brand’s daring cutouts.

Jenner, though, appeared to have worn the risky gown solely for the reception after changing Twitter users were perplexed by Kendall Jenner’s choice of blue silk bridesmaid dress, with one remarking, “@KendallJenner, “Imagine Kendall Jenner wearing this to your wedding,” one person said.

While the actress defied convention with her wedding guest costume, Perez, a social media personality, went for a more traditional bridal appearance, marrying David Waltzer in a strapless white gown.

In contrast, Bieber opted for a glitzy look, wearing a metallic Magda Butrym strapless gown and Tiffany & Co. jewelry. Perez was even seen on Instagram Stories the morning of her wedding enjoying a beverage from Bella Hadid’s co-founded nonalcoholic adaptogenic drink firm, Kin Euphorics.
