As for me, I think she has a tiny, slim & flexible body. She has short, curly brown hair and wears semi-butterfly glasses. The kind of woman you'd expect behind the desk in a rural old fashioned library. The wrinkles in her face are from smiling all day long. She only uses makeup when she goes out (but as little as possible) One exception though: she's totally into red lipstick. As for clothes: she loves her paisley blouses and pleated skirts. In her car (her trusted 35y old Vauxhall Viva) she listens to home made "The Best Of" compact cassettes. Like Abba.
Oh and the big red giant O is visible the second she reads all of the the above: her mouth with red lips will open wide, showing us a big, red circle, caused by the shock & awe moment when she realizes my description is spot on. . .
