Dang, having read this whole thread about fashion color matching, I'm going to have to hang out in Tech Talk forums for a while to get my testosterone levels back up. But buy her whatever she wants. Multiple benefits there. 1) You don't have to talk about clothes colors and styles. 2) It will make her happy, which will make your life easier and make her more likely to want to ride. 3) She can't blame you for getting her insufficient gear when she gets hurt after falling off (well, she can and will, but it will be about your riding and not also about her gear.)
