My T is a beautiful woman in her first forties.
She usually wears a big variety of dresses.. often with skirt suit, other times with nice sweaters, other times other stuff... but always in a nice fashion, at least for my point of view. Sometimes in the summer she wears a bit more formal but she's always elegant.

For myself.. I must admit that I take more care of my appearence than the normal, when I'm going to a session .
