If you want to "girly" up your biker wardrobe and are unsure where to look, check out http://www.terrybicycles.com/. Catering to women only, the site is filled with great gear for you and your bike. They have a super cute selection of jerseys, t-shirts, skorts, socks - just about anything you could want or need.
I am especially fond of the "Ride Like A Girl" jersey, tee and socks. And, they have a ton of chic designs if you want to stand out from the crowd. Also noteworthy is http://www.teamestrogen.com/ - they carry an awesome line of jerseys in every print imaginable with sizes ranging from XSmall to XXLarge.
