I just want to say that it doesn't matter who did what, to me if you were involved in any way shape or form in this beautiful manifestation you are a gift to this green earth.
You can practically find them in any color you can think of so there's no worrying about your pants not matching the rest of your outfit.
Every group has its golden child and bottoms are no different; yoga pants are that golden child; they are the unicorn of pants.
Yoga pants aren't a commitment.
Despite the thin and lightweight aspects of yoga pants, they still manage to provide you with full coverage so you have a naturally slender look.
The psychology behind it is that these pants are built for high and low impact activity so if you're going to work out in any pants because who works out pant-less that's just weird, you might as well wear these.
