Stunning sisters: Alaia and Hailey Baldwin stunned at the Endometriosis Foundation Of America’s 10th Annual Blossom Ball in New York on Wedenesday

Daring to impress, the wife of Justin Bieber looked every inch the cover girl in the couture number that featured shimmering beaded embellishment.

Alaia took her sister’s lead and turned heads in a cold-shoulder gown that boasted an intricate design reminiscent of snakeskin.

She was honored at the event alongside Molly Qerim and Fran Drescher.

According to the foundation’s website, endometriosis ‘is a disease of menstruation. It occurs when tissue similar to the lining of the uterus, or endometrium, migrates outside of the womb, where the tissue should not be.

The annual ball is ‘a night of celebration and charitable giving for the endometriosis community’.
