I also wear alot of black, and have a cat who sheds like crazy and likes to get in my lap any time I sit down. (This one's a pale orange tabby, and that hair really stands out on the black.) When I vacuum my apartment once a week, the container ends up half full of cat hair.
I always have to have at least some black (jeans, socks, shoes). I decided not to wear black shirts exclusively. (Co-workers might not understand.) But, there's always a black t-shirt under whatever shirt I have on the outside. I've even started dying the black clothes when they start to fade.
Gotta brush teeth, shower, wash hair, and shave at least once a day. The thought of missing a day on that is just nasty. Though an electric shaver on my face isn't my favorite sensation, day-old whiskers are even worse. After that, the shaver goes back on its self-cleaning station (one of those Braun models), and I sometimes splash witch hazel on my face. Like the shaver, the toothbrush is state-of-the-art, a Sonicare ultrasonic toothbrush. I don't like the sensation of the bristles on a regular toothbrush upon my teeth. The vibrations of an electric toothbrush cancel that out. Then, the head of the toothbrush gets soaked in antibacterial denture cleaner, as does the extra brush for scraping slimy crud off my tongue. Finally, I floss my teeth. That's definitely an OCD-induced routine, but it works. Better to err on the side of clean, than to go around all smelly and nasty and make people think you're weird in a
bad way.
