I like bold prints in bright colors. I tend to match my jerseys a little bit with my bike. I don't have too many blue ones anymore, since my bike is red and black.
I buy Voler jerseys or Terry mostly, which have a well fitting x small size. Voler makes full zip jerseys for women, as do several other companies. I gave up trying to buy Shebeest jerseys. They are huge on me and received a few with all kinds of defects. I like their shorts, though!
