She's a maid mare and does cleaning by day, but in her spare time she's a kinky rubber fetishist who loves to try out different gear.
She's an otherwise clean and tidy mare, always smells nice and maybe is a bit of a neat freak.
For colors i think some nice white and blue for the mane and creamy white for the fur. Still divided on the mane style here, but i guess less is more when it comes to a character that is meant to try out lots of different kinds of headgear.
