I just don't see the point personally. Yes I do suffer a bit from depression, but that's not the main reason, it's more that it takes time, money and effort that I feel best spend elsewhere.
So I have an easy uniform of comfy trousers t-shirt and cardigan, with trainers or crocs, and clean hair in a pony tail. It's not terrible, but I certainly won't win any beauty contests. But I am always ready for anything, playing out back, taking them to the park, school runs, shopping, cleaning the house etc.
Most importantly I am always comfortable, I never found fashionable clothes as comfy, nor wearing makeup easy, since it needs touched up, and styling my hair is pointless because it falls out so quickly.
It costs far less, so I don't bankrupt myself. I only get benefits and it's always a stretch, so £3 tshirts are a life saver, and I can get my trousers for less than a tenner. The only thing I ever spend big on is proper running trainers as advised by my physio. No expenditure on hair dye or hairdressers except the quarterly trim.
I do like to occasionally look nice, I save it for the few occasions I can afford to go out. I have a nice night out in October I bought a pair of shoes to wear(in my wheelchair, so the shoes are terribly unsuitable with high heels and all, :D) with a classic LBD I have, and because I don't always dress up, it's going to feel really special for me. Plus my birthday in September. Although I am having a pyjama party with my friends, so just dressing for the meal with my family. Then Christmas day. You get the idea. LOL. :D
