Having been in the lifestyle for well,over a decade I have noticed something that I feel bears mentioning.
It seems that a majority of female subs/slaves either have no freedom to dress in a manor that both enhances their physical assets or they choos not to.
I realise that in most discipline sessions Lingerie can be more a hinderance than a help, however having a slave wearing just stockings and heels adds to her sense of sexuality and can make her appear even more decadent than when totally naked.
