I’m a high school lover, and you’re my favorite flavor

A ridiculously easy way to change up or add slight detail to a standard long sleeved tee is to slightly knot it on one side.  I love this look with cut off shorts in the summer or on the beach over a bikini.  Otherwise it's effortlessly cool with denim.  Some tops come pre-knotted (like this one from Joie) and I do adore a centered knot at the base of a button up (exhibit A) but I much prefer this or that look.
