I've always had issues overheating. It didn't matter if I was underweight or overweight, I'd still sweat through my clothes. I don't have thyroid issues, and I don't have hyperhidrosis. I mostly think it's my anxiety giving me issues.
I also am very particular about my fabrics. For shirts, I've found that I don't like polyester-like material or anything that feels super silky. I've even purchased 100% cotton shirts that I absolutely hate. The only shirt I like is Costco's Kirkland Signature T-shirts. For some reason, I'm fine with most materials as shorts. I just generally don't like long sleeve pants as I don't like anything on the bottom half of my legs. I don't even like joggers or scrubs that much.
It's hard for me to figure out fashion, as I also value comfort. I've always just worn a T-shirt and shorts, and because I overheat easily, I always debate whether or not I should wear a hoodie (I find 20-30 degrees F my most comfortable temperature range). Lately, my new friends have been giving me s**t because I dress like a middle/high-schooler still (we're in a grad school program).
I really would like some clothing/style advice while navigating these issues.
I live on the east coast of the USA. I am a 26 year old male.
