Totally. If going to a sports match here and I wear a black puffer, blue jeans and rainboots I am anonymous in my style. I have been to the odd work event where I need to blend into the background and I wear my blue tailored work trousers, a black tailored fit knit top and black low heeled boots. This outfit is flattering enough, but none of the items are brilliant in their own right, it is not "in" fashion nor "out" of fashion. People would have to notice me for what I say.....or maybe my actual face or hairstyle. It is a kind of uniform.
Most of the schools here have a uniform from 11-18 years of age, and they can be rather fugly. My 13 year old wears one, but you know, because they all do, it really does not matter and removes a whole level of criteria by which people judge each other. I guess this is part of the "normcore" idea.
I think for most women, choosing not to have a style is a choice in itself, and may be to focus on their brain, compassion or career. We all know the person who is super stylish from thrift shops, or who owns a tiny closet and looks classy all the time...in most cases it is not about money. That choice is valid and I have a couple of friends and family members who fit that criteria; it is when someone does not feel that they deserve to be stylish due to a lack of confidence or body issues when it is sad.
