Hailey Bieber is celebrating her 29th year wearing leather.
Ahead of his birthday on Nov. 22, Bieber celebrated with an intimate dinner with friends on Thursday night.
Posting a photo from the event on Instagram, the model sported an all-black look with a backless top and form-fitting pants.
The beaver’s leather top was laced up the back and accented with long leather fringe down the back of the arms. The front of the top appeared to feature a high slit neck, although it didn’t look quite as easy.
The birthday girl paired it with black flared velvet pants, which are also a cold weather favorite.
Her mirror selfie included, of course, the popular Rhode Lip Case for the new orange iPhone.
Although unconfirmed, Bieber’s top appears to be vintage Versace — the same one Nicole Kidman wore to Interview Magazine in 2002.
Bieber wears both leather and backless styles all the time, so this outfit easily blends into her existing wardrobe.
At the end of October, Bieber opted for an all-leather Saint Laurent look at the WSJ Innovators Awards, and two weeks later at the GQ Men of the Year Awards, he wore a Gucci dress with a fully open back and a revealing thong.
Photos shared included a five-tier coquette-style pink birthday cake with chic martini glasses, silver candlesticks and satin ribbons.
Bieber’s dinner appears to have been mostly women-only, as her husband Justin was not seen in any photos posted from the evening.
Her party comes on the heels of friend Kendall Jenner’s 30th birthday party. The fellow model and best friend invited friends to a private island resort at the beginning of the month.
Bieber also helped Kris Jenner celebrate her 70th birthday with a Bond theme at a lavish party in Beverly Hills just a few weeks ago.
