Naomi Watts does a perfect outfit for late summer with a knee-length skirt and a basic white tee with block heel sandals. But it's time to start adding on the layers! Contrast buttons make this blazer stand out from the crowd, and this Mango blazer is $60 on sale down from $120! When you go neutral with your outfit, a bag is the perfect way to add a pop of color like Naomi did here with a green crossbody. She opted for ladylike accessories too, with a dainty necklace and pear drop earrings.
