I'm not sure if this is authentic. I was in The T.A. Signals for 15 years and did quite a few camps with the regs. The thing that struck me was that every squaddie bash I went to...a lot of them wore female clothes! And correct me if I'm wrong but there isn't a petticoat or tutu in sight!
I was sure you regulars got them from the clothing store along with your number 2's.
