At 13, my folks went on holiday, leaving my brothers and I in the charge of my sister, older by about 5 years. Mom had left two bikinis behind, one red, one blue. Some of us tried these on for a laugh one day, but it only affected one (that I know of) deeply.
Later in the holiday, the others dressed me up for a laugh and sis did my make-up: the joke was that I would meet a friend of sis's off the bus. I wore her bra (but not panties -the others wouldn't buy it), tights, half slip, and a lemon button front summer dress. Sis did my make-up, and I stayed in those clothes long after it was necessary.
