You are up very early snail!
Me too! I am 'curvy', and I have trouble finding running gear. When I started I was a size 18, and there was no chance of finding anything. Big cotton t shirts were the order of the day.
Now I have lost some weight, I can fit into a size16, I have some options, but I still find that many ranges of sports clothes only go to a size 14.
It's just another excuse for fat people not to go out and exercise. Surely, us larger ones should be given all the encouragement we can get to get of our buts and exercise. It would be nice not to be made to feel like a freak when you are just starting out, by being unable to find any clothes that fit!
