My wife would assure you that I'm not. Can't think of the last time we went somewhere that she didn't "suggest" that I change clothes first.
My husband has two fashion sides to him..... the professional (which I pick out, other than his suits), and the "home," where it's hard to distinguish between his dress and your average vagabond. ^-^
Basically, I'm not that interested in fashion. When I watch models wearing the newest fashions, I pretty much always think they look stupid. I seriously am more of a jeans and sweatshirt kind of woman.... and have been since I was a kid. I dress fine to go to church and teach my classes and have a few nice things for professional social engagements, but otherwise, I'm extremely casual.
The whole thing is too much trouble, IMO. And WAY too expensive for my frugality to indulge in.
