Cool Coat: AG Adriano Goldschmied Women's AVENALL Jacket
As someone who owns several jean jackets, I firmly believe that this layer can bring an effortless cool to any look. But, since a person can never have too much denim, I'm low-key obsessed with AG Adriano Goldschmied Women's AVENALL Jacket ($150). The white buttons and contrasting threading throughout gives this coat an elevated, compliment-worthy edge. (Translation? It's the perfect thing to wear when it's not too hot, but not too cold.)
