Wear a rainbow wig, a tu-tu and an ‘it’s not grooming if the child is transitioning’ tee shirt, men with beards - wear red lipstick and a diaper or a big tail. Women - shave your heads and wear a wifebeater and have an angry, sexually frustrated scowl on your face.
Color your hair blue or purple with a temporary dye. Kool-aid hair rinse? Wear over-sized reading glasses. Buy bright colored sneakers from Good Will that can just later be dropped back into the donation bin.
