Okay, so I know some girls wear thongs every time they wear these pants and some wear boy shorts. I wanna know, guys when you look at a girls ass in yoga pants or leggings, can you tell if she's wearing a thong or boy short underneath? Which one do you prefer your girl to wear under?
Of course you can tell. Yoga pants aren't much thicker than a coat of paint, so anything you're wearing underneath would be visible, even IF the yoga pants weren't partially transparent, as many are.
Now, I don't find VPL a huge sin like some people do, but let's be real: the ONLY reason girls wear yoga pants is to show off their ass. You can say "oh, they're comfortable" all you want, but lots of clothes are comfortable without being shrink-wrapped to your ass. I'm totally fine with it if you want to show off your ass, but let's not try to pretend they're for any other reason, UNLESS you only wear them to work out.
I'm normally a fan of regular bikini-cut panties over thongs, but even I might say "thong" when wearing yoga pants. Because, if any clothes in the world were designed for thongs, it's yoga pants.
Sometimes yes, one time I saw this one woman who was a little on the large side wearing yoga pants and they stretched so much it was clear as day that she was wearing a thong.
There was another occasion when I saw this one girl with a much nicer body who I could tell was wearing bikini panties under her yoga pants, it was kind of hard to see but I was able to get pretty close.
Doesn't matter to me what she wears under them, I trust her to be tasteful :)
There are some fairly transparent yoga pants that reveal the kind of underwear underneath if the underwear is a contrasting color to the pants. As for the kind of underwear I like, thongs are hot but only if it doesn't seem like the girl is showing it on purpose.
