I think that if you want it, you should totally buy it! IMO there is nothing wrong with a guy carrying a handbag at all. You're the one who's going to be carrying the bag anyway, so all that matters is that you love the bag, and since you've been obsessing about it, it seems that you do love it! So buy it, and make sure you post pics, hehe.
After seeing pics of other guys carrying it, I am totally considering buying one now too! (I'm a guy)
