Yes we can notice. Duh! It's tight against your ass. Thongs show up less but we can still tell that you are wearing them. Regular underwear shows its lines like where it ends at and major creases etc...
NEVER wear underwear with yoga pants. I know this sounds perverted, but guys LOVE to see girls sexy butts under those pants. And the hottest thing is when you stretch on the floor and they can see the outline of your vagina. Next time your near a dude, do a split and then casually touch your perfect pink through the yoga pants. The guy will get rock hard right there guaranteed. You're welcome
Yeah, I notice pantylines if a girl is wearing yoga pants, and it isn't attractive. But if a girl is in yoga pants with a great ass and no pantylines? That's unbeliveably hot! I've never gotten a full blown erection from it, but I've definitely felt myself getting longer. Probably not what the girl intended, but there it is! Hahaha!
i hope this dosnt offend any of you ladies,that is not my intention.with that said,i personally find visible panty(granny full) lines,a complete turn off.this is from a guy that LOVES yoga pants on women.when a women wears granny panties it says "inmature and completely lacking in confidence".even if you wear a thong,boy shorts,sheer panties or even better none,to me that says "im sexy and I know it!".there is nothing sexier than a confident women.just my $.02
I never wear anything under my yoga pants, I don't care about the pantylines but I do love the free feeling I get from wearing just the pants. I buy my pants at Mesa Yoga Apparel and Studio which carry a very light weight and sheer material made up of a combination of fabrics they manufacture. It actually feels like your not wearing anything and there is no tension in the material expansion during positions. They carry form fitting and loose fit baggy crotch types. I love both. I have been told by many people during and after classes that were behind me that both types of pants become very see through during stretches and that I should wear underwear because they can see everything as if I wasn't wearing anything at all. I don't care and kind of enjoy the attention. I enjoy watching the guys jockeying for positions behind me before class starts and the owner has told me that the amount of men attending classes have increased since I've been coming there. I told them they should have a coed nude class.
