Madewell Denim Over-sized ex-boyfriend shirt Hutchinson Wash blue, medium

Madewell Denim Over-sized ex-boyfriend shirt Hutchinson Wash blue, medium I tried bleaching the shirt to lighten the color and it left some darker splotches (see pictures). It probably can be bleached more to even the color. The fabric is cotton. Other than the discoloration the shirt is in great condition. I only wore it a couple of times.
