I suddenly feel the need to wrap myself up in a cozy, warm chocolate brown overcoat. Full disclosure: it’s not just because it’s October and there’s a chill in the air, it’s because I spotted It Ends With Us star Blake Lively wearing the perfect look on Instagram. Sure, the point of the post was to promote her recently-launched Blake Brown hair care line (more specifically, the brand’s All-In-Wonder Leave-In Potion , which you can shop at Target ) but it really was that chic longline coat that got my attention.

Channeling Serena van der Woodsen from Gossip Girl in the series of snaps, Blake rocked tousled I-woke-up-like this bedhead hair and styled the coat shirtless, wearing only a pair of jeans with the oversized overcoat. With the temperatures dropping I think in real life some more practical styling might be a little necessary - but that minor detail aside, I loved this look so much I went on the hunt for some dupes! The inspiration: Blake’s a huge fan of designer labels from Oscar de la Renta to Versace, but I thought I’d look for something at a bit lower price point. As it turns out the star's coat is right on trend, so there are a few great options to shop.

Shop the look: Top of my list is this chic overcoat from H&M, which has the same vibe but without breaking the bank. The $99 / £84.99 maxi coat is a modern classic, with notched lapels, a tab and button at the cuffs and a high cut vent in the back.

The fully-lined piece is single-breasted with strong .
