I found a great source of pin-up style women and burlesque poses in these out of print 1950's vintage book covers. These detailed, stylistic illustrations were meant to be about sexy, racy (at the time), out of control women, and to be intriguing to men in a way the Bad Girls Club cannot. Less is definitely more.
The covers are translatable to photographs easily, and I will certainly try to emulate them in the near future when I need a throwback look or want to try something different.
