Some years ago I stumbled upon a software that allowed me to paint digitally, and when I say to paint I mean it. The color mixed naturally and the brush felt so realistic that I couldn't stop painting. Every time I was stressed, or had some time off I picked up the brush (the mouse actually) and clicked away the stress, pouring color on the digital canvas and creating figures and shapes.

Pin up girls weren't on my radar yet. I just wanted to learn how to draw the human figure... since I was almost decent at drawing still lifes.
Female body was my first option for several reason: is more difficult to draw, is more harmonious, is more pleasant to my own eyes! So I looked up for pictures on the web, focusing on the human figure where the background was barely visible. One picture that I liked a lot was this Sport Illustrated shot - It felt really interesting to me, how the skin reflected the light, the overexposed water surface, the way her wet hair looked... so there was a lot going on in that image. I had many things to memorize, a lot to learn and practice with, plus... Bar Refaeli was really nice to stare at! :-)

You can see the the final result here.

That was my first attempt to paint something that is pretty close to what pin up girls used to be back in the days. Still, I was not aware that I was going to fall deeply in love with them thanks to masterpieces of Elvgren, Vargas, Driben, Withers and many others.
