I wear a dress or skirt almost every day., and most always I have a half slip on., It makes what I'm wearing sit better and allows my dress or skirt to swish around easily (no clinging).. Also guys seem to enjoy the seeing a bit of lace hem peeking out..
I wear one most days anyway under my skirt so no big deal.
As a guy , I too prefer to see my girlfriend wearing a slip under either her skirt or dress.
I wear a half slip with skirts and full length petticoat with dresses, standard attire for ladies.
Definitely...feels like a glamous movie star...not too much left these day to the imagination...
I prefer that neither of us is wearing anything at all.
Sorry no imagination babe, think a little bit of mystery.
