I eventually switched to covering up everything when I go to yoga, if for nothing else than because DC summer class in a third story studio with broken A/C meant things got real slippery without long sleeves.
To that end, I wear a very long clingy tank top (so that I don’t expose anything when upside down) from Costco, a unisex long-sleeve shirt with high collar, and black ankle-length yoga pants from Athleta. The pants are 2 years old and fine, very little stretch or sag. I practice 1–2 times a week fairly consistently.
Will also throw out there that I love my Prana mat. Left it in the sun for 5 hours to break it in when it was brand new, and it’s been perfectly grippy without smelling for years. Lifetime warranty, too.
