Katy vs. Dita

So anyone who knows me, knows that I'm really BIG on retro, I love history, and I really LOVE the 40s and 50s. So it should be no surprise that I would like Katy Perry and Dita Von Teese. Katy is on the cover of Vanity Fair right now, looking ever so lovely as a 40s pinup model. But there Dita is wearing almost a similar look, so I couldn't choose who wore it better, I think they both rocked it, my only thing is is that Katy's corset looks like it's going about to fall off of her. Katy looks extremely seductive and sexy. Dita looks very classy and the look and hair reminds me of Jane Russell (R.I.P.) So who do you think wore it better?
