I want this so bad! You can either wear an under shirt of any color, or sew a color under the ripped heart. The shirt also has a slouched shoulder, so i prefer a tank top instead of sewing under the heart.
Buy a mirror. Put letter stickers on it. Paint over the whole thing. Peel off stickers. (use canvas instead of mirror. Paint canvas what color you want your letters to be first, then letter stickers, paint over, peel off)
