I don't think it looks girly. I don't think the white does, I just prefer the black. But man, that gold is sharp. Really making difficult for me to decide between that and the space gray. If only there was a gold option with black glass...
I really really thought I was going to hate the gold, but having the slate iphone 5 I was planning on going silver/white on the 5S and now the gold is growing on me like crazy.
Who cares if people think it's girly? You can't please everyone. There will always be people who will find any reason to make fun of you. Just get whatever color you like.
I thought I was going to hate the gold version, but it's rapidly becoming my favorite. I have a feeling it looks much better in person. But I have to be real with myself... I'm 99.9% positive that I'll be putting a skin on it anyway.
