Everyone needs a long trench coat in their winter collection. Not only do they add an effortlessly chic touch to the most casual ensembles, but they're ultra-warm, too. Mila Kunis is the latest star to style the timeless jacket in a cozy-girl-inspired outfit. The comfy-posh jacket was the star of her look, so we found a polished lookalike on Amazon that costs less than $60. Like Kunis' winter pick, this navy blue coat boasts a maxi-length. It instantly elevates a hoodie and sweats or complements an elegant winter outfit.
