I ended up getting a pair of mens XL cycling shorts on clearance. I'm normally a size 12--so if you are smaller, you may only need a mens Large. They were great for pulling up and over my tummy--sooo comfortable and less expensive than buying specialty shorts.

For jerseys, I wore DH's old worn out ones, snipping the elastic waist in some of them. Otherwise I wore t-shirts or got some cheap workout tops from Target.
