Hailey Bieber (neé Baldwin) stunned in Versace at the Vanity Fair Oscar Party on Sunday.

She attended the red-carpet event in Beverly Hills, California, wearing a sheer gown made with patterned lace. The bodice, for example, featured a criss-cross design, and its skirt was covered in speckled squares. It was also embroidered with black Swarovski crystals.

Bieber’s outfit also included a see-through long-sleeved shirt that looked like it came out of the ’90s, when it was popular to wear a dress over a top. It’s not clear if the top is part of Baldwin’s Versace dress or a separate piece worn underneath; representatives for Baldwin, Versace, and stylist Maeve Reilly did not immediately respond to Insider’s requests for clarification.

When she turned around to pose for photos on the red carpet, Bieber revealed that the back of her gown was also semi-sheer. She completed the look with platform sandals and jewels from Tiffany & Co.

Bieber's makeup looked equally stunning. Makeup artist Mary Phillips created her glam style, which included nude lipstick and black eyeliner. According to an Instagram post from the artist, Bieber's look was inspired by a "'90s Barbie." She used products from BareMinerals, as Bieber is the face of the brand.
