Just an added thought: the "forced" wearing of lingerie can fit into the humiliation genre of a domme forcing her sub to humiliate himself to prove how badly he wants to both be allowed to pleasure her and ultimately be allowed to achieve his own pleasurable release.
My two cents.

I agree with you with this 100%. Being instructed to dress or be "feminized" is very hot when done in the context you mention. Dressing also works well in slut-training and role play scenarios, though I suppose one could categorize one or both as offshoots of humiliation.
What's funny is that I would think this would be one of the more 'tame' and 'easier' fetishes that a provider could indulge their client on...but there are a quite a few local providers that just say no to this.
