It must have been pretty chilly out when Blake Lively (Serena) stopped by the Late Show. The leggy actress, who’s usually a fan of itty bitty cocktail dresses, opted for slim fit jeans, a button-down, a leather trench, and a scarf. That’s a lot of layers for the same woman who regularly employs strategic cutouts to show off even more skin than her revealing outfits already display. Of course, we couldn’t be more pleased by Blake’s autumn-appropriate look — after all, we can’t pretend it’s summer for much longer. We’re loving the subtle ‘70s of vibe of Blake’s caramel-colored leather trench, and we approve of keeping the reference subtle with contemporary skinny jeans. All in all, this is a look we’re happy to copy as the leaves begin to turn, and with our handy guide, it all can be done without dipping too far into your seasonal savings.
