A few years ago, DH went to a local sporting goods store (a chain) on his way home from work, to get a couple of yoga mats when we were starting the Cyclo-Core program. He got one turquoise and one pink, just so we could differentiate them.
Then, I started going to yoga at the gym or at a studio. I was embarrassed by my bright pink mat! So now, I take the blue one. Mine seems to be thicker than the ones I see others carrying.
I could care less about graphics on a yoga mat. I definitely don't like girlie stuff, but I am not opposed to pink on jerseys or socks. I will wear a bright color top with black pants, skirt, or a suit, but mostly, my regular wardrobe is black and gray, although I have been told I should wear jewel tones (in the '80s I did).
My DH has several wild looking jerseys. Much wilder than mine.
