Looking for one old hz locker room movie - one of a kind

[lightness]

Hello.
Maybe You will be able to help me. Few years ago I saw old hz locker movie (not hd) on which camera was placed somewhere low, probably on floor of pool/fitness locker room and there was lady passing near it with visible open crotch pantyhose (something like stockings with garter belt but in one piece) under her skirt. Do You know which movie could that be?
I am looking for it since months now.
Regards.
