I'n well into middle age, and I've always worn something of a "uniform." I have many sensory issues and have always been very sensitive to fabric and touch. (As a child I had a "picky blanket" I would carry and rub between my fingers.) If I shop in a store, I eye the garments because if I touch something I don't like the feel or scent of, I will have a visceral reaction. I have not been able to tolerate tags since childhood, and I am mindful of interior stitching and seams and how that will feel over a long day. I stay away from all fussy ornamentation. Lots of black clothes but will occasionally wear olive green, burgundy, gray, maybe navy. Currently, I mainly wear pull on corduroy pants with an elastic waist from Uniqlo. I have four of these and will probably get more. They are soft, fit well, comfy and I can forget I'm wearing them. I wear long sleeve thin V neck cotton tee shirts from J Crew and a cardigan sweater, cashmere or merino wool. If I have to do in person business, I wear a black wool jacket over everything. I have three identical jackets and some others. I wear black lace up leather sneakers and oxfords. I have a couple pair I bought this year to replace four pair of identical leather and net soccer type sneakers I had for about 7 years. I have black Timberland boots for snow. Just started wearing Champion fleece lined narrow leg sweatpants with pockets to work at home. I wear nice quality socks, no noticeable seams. Sometimes my wool socks will get bunched up wool inside and if I can't get it off with a shaver, I can't wear the socks. My shoes always need to be tied to exactly the same degree of tightness for each foot. Summer, I wear chino shorts in black and a few other colors and J Crew short sleeved linen and cotton tee shirts with sandals with an ankle strap and covered toe and heel. Have a couple pair of those. Sometimes I wear black cotton tee shirt dresses or sun dresses. I pretty much won't wear anything I couldn't comfortably sleep in. I just moved after many years in the same apartment and it felt great to get rid of half my stuff. I will only use or wear certain things and now I'm not going to try to go beyond that. I like knowing brands, because then I know fit and feel and can buy online, a couple at a time during biggest sales. (I buy $70 shorts for $7.) I hate when something is discontinued or the manufacturer changes the "formula." I have a couple black winter coats. I want to get a black LL Bean boiled wool coat when they get way marked down soon ($35 v $150), but I'm not sure I want to accumulate more stuff.
If I shower, dress and leave my house shortly thereafter and walk briskly, I often have an all over body reaction with hives, itching, etc. it may be from pressure of clothes on especially tender skin, tiny unnoticeable body hairs being crushed under fabric, etc. It's almost unbearable but will usually abate in 15 to 30 minutes. I try not to dress or leave my house too soon after a shower. I do have quite a system but I need to to function and not be miserable.
