The Bieber family (especially Justin) is notorious for wearing house slippers instead of real shoes. So it should come as no surprise that their gaywear is bedtime appropriate for Christmas, an official pajama-themed holiday.

Instead of attending the Kardashian/Jenner family holiday party, new parents Justin and Haley celebrated Christmas mostly away from the cameras. The only evidence of their holiday behavior was a few snaps on Haley's Instagram Stories.

The model shared a photo she dubbed “Christmas Cosies.” She was super casual that day, not even bothering to change out of her PJs. Bieber wore blue striped boxer shorts (possibly her husband's?) instead of real pants.

The whimsical co-ord sets, which cost $70 and $235 respectively, are from Tekla, a Copenhagen-based brand. The brand specializes in Scandinavian-style homeware, including bath towels, linens, and sleepwear, most of which are made from the same fresh striped fabric.

Although she did not post a full-body photo of her Christmas fit, Bieber did release several detail shots that hint at her overall look. In one of them, she shows off her signature glazed donut nails while clutching a Grinch coffee mug. In the same photo, Bieber also shows a bit of professional layering, wearing a gray T-shirt, an oatmeal-colored sweater, and a poplin shirt that matches her Tekla loungewear.

Bieber's holiday attire is part of the TikTok viral aesthetic that has been trending since last summer. In particular, her striped boxer shorts jumped out of the Scandi Girl playbook. Dua Lipa also tried this look last October, pairing a cherry-print bikini with similarly patterned shorts.
