Haley Bieber's post-pregnancy fashion era is in full swing, and since the birth of her son Jack Bruce in August, she's been out and about in tried-and-true, statement-making outfits.

Bieber is also one of Hollywood's top trendsetters, and with fall just around the corner, she's gotten her fair share of experimentation. Her latest street style incorporates the trusty no-pants look with a transitional wardrobe essential: the oversized barn jacket.

Bieber was photographed on September 10 in Los Angeles, where she went for an evening stroll with friends. She was seen wearing a tan suede baggy jacket with a sleek black leather collar, wide sleeves, and huge front pockets. In a recent image taken of the jacket, Bieber shows a pair of black micro shorts peeking out from the hem of the jacket, although not much is visible under the jacket. The look was also a close copy of a pantsless burn jacket outfit she tried on over a year ago.

Her footwear was not in focus on this occasion, but given her choice of combed white crew socks, we can only assume that the Road Beauty founder chose her customary black loafers or a pair of comfortable It sneakers.

She accessorized with chunky 80s-inspired gold teardrop earrings and a $2,990 leopard-print hobo bag from Saint Laurent. She opted for a discreet black face mask and styled her brunette hair into her signature slick-back bun.

The burn jacket trend is gaining momentum ahead of fall. Stars like Katie Holmes, Kendall Jenner, Dua Lipa, and now Bieber are taking on this outdoor jacket for a reason: It's practical and versatile when paired with the right silhouette. Revamped in high fashion by brands like Prada on the runway, the barn jacket is also being revamped by traditional brands, from L.L. Bean to J. Crew.

Haley Bieber is always a styling inspiration, and her play on proportions is one way to wear a barn jacket, a style that is everywhere. But don't be afraid to swap your casual jeans for a maxi skirt.
