Hayley Bieber is a veritable connoisseur of oversized leather jackets. Her collection is extensive, but her latest purchase may be her best yet.

After celebrating the launch of Rohde's new Barrier Butter earlier this week, the skincare founder bundled up in a Saint Laurent dark brown bomber jacket for sushi with friends at the Beverly Glen Mall on October 9. We've seen her wear this jacket twice before, both times in the past. It combines the asymmetrical design of a biker jacket with the blouson sleeves of an aviator jacket. Most memorably, she paired it with yoga pants and kitten heels while attending church with her pop star husband Justin Bieber in August.

But I'm a sucker for the coffee-colored version. It capitalizes on the fall chocolate brown trend and the bomber jacket trend that seemed to adorn every editor's shoulders during Fashion Month. (Of course, if you're not ready to invest in the trend just yet, similar styles from Agolde and L'Academie will help you recreate this vibe at a more accessible price point.

This new mom goes for a monotone look with her go-to jacket and brown pants. She accessorized her ensemble with a hunter green Yankees baseball cap, silver hoop earrings, and this season's celebrity tote bag, Saint Laurent's black Le 5 a 7 Hobo Bag. Marie Claire's fashion features editor, Emma Childs, also rated this style as one of the best YSL bags. But the detail I'm most taken with is her black square-toe ballet flats.

Zoom in and you may notice her clutching an unreleased espresso brown low drip case that is expected to drop this fall. Nevertheless, Bieber's best accessory will always be her nails. She's currently rocking her signature glazed donut manicure in a fall-inspired latte color, but we already have the scoop on what fall manicure trend she'll be trying next.
