ICYMI: Boyfriend blazers are the ultimate fall wardrobe staple - and we have celebs like Julia Roberts, Amanda Seyfried, and most recently, Margot Robbie to thank. The Barbie actress wore an effortlessly posh look, layering a plaid boyfriend blazer over a white T-shirt and jeans. While we don't have the details on the one Robbie wore, we found a luxe lookalike to achieve her buzzy look for less than $50. See it! The Ebossy Houndsooth Boyfriend Blazer channels Robbie's preppy style with a price tag that will make your bank account smile.
