It's only important to get a Women's Specific Design bike if WSD is what fits you best.
After you've ridden a few, you'll get a feel for the type of geometry you like.
WSD doesn't feel right to me, but cyclocross geometry feels lovely for some reason. (I've bought 3 cx geometry bikes in the last 2 years.)
It's all geometry and magic.
Having a label like WSD, Cyclocross, Cruiser, Touring, Racer, just gives you a nice short-hand way to describe the general geometry you like best, which helps you when you go shopping. But you probably have to go shopping to get a feel for what you like best!
Ride lots of bikes! Ride everything!
