Public display of my submissive as such is an absolute necessity in our relationship.
She is required to wear an impossibly short miniskirt in public, and is never permited to cross her legs when sitting. Also, never a bra, as her breasts are quite tiny but her nipples fairly large, so it's a nice look.
And collar and leash at all times. I may or may not lead her by the leash, depending upon where we are, but she always must wear it nevertheless.
There is no dress code at home, as she is always kept naked.
