...because that was how I was comfortable dressing. I didn't dare to wear leggings, because I thought my legs looked weird. I didn't dare to wear anything that showed my arms; if I had to wear a t-shirt, I'd wear a longer sleeved one underneath it. I have what I assume is a kind of eczema, where my skin - but particularly my upper arms - bubbles up in little red marks, especially when I'm too hot or sweating, or itches to the point where I have to scratch and it scars. And I'd become convinced that every time anybody looked at me, they would notice it and go 'ewww'. So I kept it covered up as best I could, even if it meant boiling during summer.
Going to roller derby for the first time was massively daunting, and not just because I'd never been on skates before! I'd followed advice and worn what I thought was tight clothing, but which probably wasn't by anybody else's standards, and I felt like I was going to walk in and all these athletic looking women were going to take one look at me and laugh behind their hands. Yes, yes, I know. It was a stupid thing to think, but at the time I'd convinced myself that it was entirely realistic.
I don't think I've ever been so wrong in my life.
