We’ve covered the varsity jacket trend, but for warmer days, layer up with the letterman sweater instead. We love the chic combination of this lovely Parisian lady’s baby pink “A” knit with tailored trousers and classic pointed toe pumps in purple for an expected pop of color. Her preppy look has a hint of edge with an exaggerated pair of cat eye sunglasses and a beige pout. For a more casual, school-cool type look, choose a letter cardigan with a block letter, like this “M” sweater from Wasteland, and an old school slouch beanie. Go all out and add a pair of over the knee socks for the ultimate throwback ensemble.
