If you're looking to have a business relationship with someone surely you should simply require them to be good at their job. They don't need to have dry hair, make up on, a nice bag. Presumably the more time they spend on their appearance the less they spend on doing the job you require them to do.
Similarly if you're looking for someone to have an emotional relationship with. You need to get on with them. Surely whether or not they've ironed their t-shirt shouldn't be a consideration?
Why is it the case that humans, often, try to find someone who spends time on their appearance? Even on MN where there are so many feminist viewpoints the majority of posters still expect professional colleagues to look like they've made an effort.
I don't understand why these things are important.
