Yoga pants are for people who are going to do YOGA. They aren't for people to wear as casual wear for fuck's sake. That's like me dressing up as a construction worker or doctor and go "what? no this is just a comfortable outfit. Don't be so judgemental...."
If you are wearing yoga pants, GUY OR GIRL, and aren't on your way to or from a yoga class, I wish your demise. I wish some dad who finally got fed up with life started driving like a lunatic and running people down and you were one of them.
You'll get over this as time goes on. I predict more stretchy-type casualwear in the future. It's nice being able to move naturally! Restrictive clothing is lame. And yeah I bought it for yoga, but on my yoga days I wear my yoga pants alllll day! Because I'm not driving home to change or bringing other pants when I don't need to.
