We seem to be about the same size. I got my jacket at REI. It's a men's large and the sleeves are long but they have cuffs that keep them in place pretty well. I use a construction worker vest in hi vis yellow. It is mesh and keeps me visible and cool at the same time.

Now for Bras...any suggestions? Please don't say title 9. They do not have fat chick bras at all! I am ready to go braless until I really gross enough people out that someone will make a decent sports bra in a 42!!!! Sorry to steal your thread, I am in the throws of shopping sadness!
