Sorry the quality isn't the best, but pay attention to the back of her shorts. Orange, intact. Now watch from after she takes a spill trying to springboard off of the ropes, when she falls. Definitely has torn shorts and exposed white panties. 4:50 or so, we get a close up on her ass and it's especially obvious.
This one doesn't seem to get noticed a lot, being on Sunday Night Heat and I guess not being obvious to some, with no emphasis put on the exposed underwear, so it gets overlooked.
