I live in the UK and I wear Topshop and Jack Wills. It's just easier. It's pretty expensive (Jack Wills- £60 for a sweatshirt, Topshop- £40 for jeans). Oh, except I wear these baggy woollyM&S jumpers I get from charity shops or from my dad
I'm constantly aware of my clothes, once I got worried that I had lice crawling everywhere because I kept having to touch my clothes and stuff. There's not much I can do except cover up, because things like a hair falling on my hand or a crumb on my leg is much more annoying/almost painful than fabric. In summer, though, I just wear castoffs- shorts, a top, skirts, old shoes. That's best
Somehow it doesn't bother me when I'm outside running around.
