So, that chick in the cafeteria did notice your new shirt and you’re meeting her for some real coffee—outside of the office—and you need to keep up with appearances. We’re sure you’ve heard this before but horizontal stripes are your best friend. Hey, if it ain’t broke, don’t fix it. ASOS’ Polo Shirt in Heavyweight Stripe with Woven Collar ($25) combines a classic go-to style with a trendy colorblock that isn’t too over the top. The cotton has a slightly heavier feel to add some bulk.
