Dear, oh dear, oh dear.
Burlesque is an erotic performance art form, very controlled, quite provocative and very different from stripping.
I watched television clips of Dita von Teese performing, definitely very artistic, and also someone I knew who was persuaded to perform for a hen do among friends. (she also learned line dancing and go-jo, mo-jo (?) or something similar.
We were invited to have a go at learning basic moves and it was good fun; I can understand the WI enjoying it. I think I was mid-fifties at the time and won approval from my much younger colleagues at the time.
It is possible to be a feminist and erotic at the same time, but rather sad that people condemn it without have ever seen it.
Still, each to each her own.
