I found the patterns at a site called the green pepper:
http://thegreenpepper.com/
Its on the adult pattern page...just "Women's Cycling Jersey" and "Oregon Racers" are the shorts.
I found a few sites for lycra and activewear fabrics too:
http://spandexworld.com/

Let me know if you also try to do this-with the right pattern and fabrics I think it would be a great project and totally do-able!
I'd love to customize the jersey (and shorts if I get the nerve to make those) and have a one of a kind outfit!
