It has been said that Albert Einstein had a closet full of suits. and casual clothing All the same so he wouldn't have to waste valuable thought on deciding what he was going to wear.
I don't own a single outfit, but i DO have a distinctive personal style, and i find that it simplifies my life enormously
My chosen colours are red and black, though in formal attire some other tints creep in. The style is primarily asian. My hair is worn Up, but with one fall or plait down the back, and some curls framing the face. I always wear glasses, usually tinted, and small lenses. I only wear shoes with casual or business attire, when dressed formally, i'm always barefoot.
The benefit of having a singular style is it allows me versatility in appearance while maintaining a very recognizable character, Also, it is far more economical, as one is not purchasing every new and shiney thing one sees, One becomes selective. I've met people who arrived in SL from other platforms i used to occupy, and they have recognized me in a crowd very quickly despite my change of name and our long seperation.
The Einstein route may be the most economical in time and money, but with the rapidly changing styles, AND the increase in quality of newer clothing in SL, I don't think i could stay in one single outfit ad infinitum.
