Her Broadway play, Dead Accounts, may be closing seven weeks early, but the shortened run certainly hasn't dampened Katie Holmes's off-duty styling mojo. And today's latest fare is further proof of her reign as a consistently cool styler of casual wares — right into the New Year. We could easily give all due credit to her gorgeous long, blue, double-breasted Balenciaga coat for making her outfit both Winter-appropriate and classically chic, but where's the fun in that? No, we're also looking to Katie's no-fail skinny jeans, black turtleneck, and black suede ankle boot trifecta for an additional round of "what to wear when it's cold and not look like a blob" inspiration. While it's almost second nature at this point to reach for a darker denim wash, try a lighter iteration for a boyfriend feel without the boyfriend silhouette. Then, layer up on top. Translation: a turtleneck, tee, and coat are all par for the course — as long as each piece fits correctly and is tailored close to the body. The whole look feels put-together without trying too hard, and the best part? You really don't have to try very hard to achieve the same kind of Katie Holmes effect.
