Bored of black shorts

[sundial]

Where it says I would need a large, I actually fit in a medium. So not quite sure...

I usually buy a short one size smaller so that the chamois doesn't pinch or bunch up on me.

Have you considered trying a skort? It's pretty handy wearing one when you jump off the bike and runn into a convenient store without looking like you've got a maxi pad sewn to your shorts.
