How I look affects how I feel and how i present myself to the world, online and in person.
Age discrimination and the halo effect are real, and I want to keep myself employable as long as possible and perceived as competent and trustworthy at work. (

Beyond these effects there are exactly two people on this planet who matter when it comes to my appearance. Me and DH. We both work from home and he notices when I put on a (cotton, easy, comfortable) dress and wear a little makeup. He might not even know he notices anything in particular but he responds differently. This is important too.
