If you asked us our favourite thing about this adidas t-shirt, we wouldn't be able to choose between two: the oversized, boxy silhouette and that surprise houndstooth in the Trefoil. With that out of the way, let's talk details. The ribbed crewneck keeps things tailored up top, and a blend of cotton and elastane is just the right mix for all-day comfort, anytime. Pair with leggings, denim or tight-fit shorts.
