Leave it to the internet to juxtapose classic pin up girl illustrations from artists like Alberto Vargas and pictures of cats similarly-posed. Ooo la la. Now there's a site that is a one-stop shop for Cats That Look Like Pin Up Girls (may be NSFW). The site was put together by Hurly-Burly Clothing in Perth, Australia, perhaps as a means of drawing attention to their quirky clothing store via viral Tumblr goodness. Well, it worked, you devious Aussie clothesmongers. Now find more pin ups who look like Grumpy Cat. The internet demands it.
Our 25 favorite cats that look like pin up girls are collected below. We stuck with the safe for work ones only. (We even had to photoshop Marilyn Monroe's nipple out of the banner picture. Sorry.) You can head over to the sometimes-NSFW Cats That Look Like Pin Up Girls for the rest.
Thanks to Nunaya for the tip.
