Fashion, Or Something Like It

It's always a little awkward "in real life" when friends introduce me as, "this is Rebecca, she's into fashion." Although I run a fashion site (I'd actually specify this as a personal style blog) I would consider fashion only one of my interests...possibly a lesser interest than books or art--fashion just happens to have a much easier visual representation than my other passions.
Outside of that there is the question of what do you mean by "interested in fashion?" I think it's often used to mean an interest in shopping and dressing yourself "cutely," which aside from antique malls I actually sort of loathe the shopping experience (malls suck). If someone is interested in sports though it isn't described as a humogenous group--someone interested in soccer isn't automatically assumed to be interested in baseball or football. Similarily, fashion is just as diverse. Are you interested in personal style, or do you follow runway collections, or perhaps is it fashion photography that really inspires you? If it is personal style, do you enjoy following trends or do you like some particular sub-group like grunge or goth or vintage looks? Someone interested in trends is at a vastly different end of the fashion spectrum than someone who predominantly dresses from a specific past decade. This isn't to say one is superior to the other, or liking to shop is somehow more shameful than appreciating runway collections. The point is: fashion is actually a really broad, diverse term and not a proper description of someone's passion. So yeah, it feels awkward when it's how I'm introduced and I watch all these conceptions gather in a stranger's face and wonder if any of them actually suit my interests and passions. I do love fashion and I'm not ashamed to list it as an interest, I just wish I could always be precise...
