You don't say where you are. The law differs in England & Wales, Scotland
and Ireland. Having said that, I don't see there being a problem in the
context you describe, even under Scots law.
I'd be surprised if colleges set up classes in a way that could draw
complaints from outside observers.

No.
I can't imagine a college holding a life class in a room which can be seen
into from outside. But even if they did the answer is still *no*.

Not a problem I've ever had. But I can't see you getting into trouble over
this unless you were deliberately flaunting yourself. Far more likely IMO is
that the teacher would get a handle on the situation long before it reached
such a situation. Suggesting a break for example. And if some "mischievous
students" were provoking you the teacher should be aware of that as well,
and do something about it!
