Ana, shorts are a lot like saddles. What works for one woman, might not work at all for the next. I started with Pearl Izumi Ultrasensors, but moved onto Sugoi FS shorts after PI redesigned the Ultrasensors. I ended up ordering and returning a number of shorts, before I finally just called TE up, talked to Susan at length (thanks again btw) and ordered the Sugoi's on her recommendation. They're the only short I wear now.
Short of doing it by trial and error, you might call TE and just see what they recommend based on the type of riding you do, your anatomy, your preference for length and fit, etc. When I say anatomy, some women find that they need a little extra padding for their girly fits because of how much soft tissue they have. Others need extra padding for their sit bones. Still others need both.
As a general rule, I think you more or less get what you pay for in shorts. So, while some of them are pretty darn expensive, they can be worth it if you ride a lot.
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
