Z Supply modern slub tee in black. Your closet needs the Modern Slub Tee! This is a casual wardrobe base-layer essential made from our classic Cotton Slub Jersey fabric. This effortless top is meant to hit at the waistband of high rise styles and can be worn tucked or untucked. This tee is meant to fit closer on the body, so if you prefer a looser fit, we recommend sizing up.
