Just my two cents, but I've been coaching 10+ years and my oldest is playing 18 yr old ball. Girls seem to prefer the Mizuno low rise. I'm not explaining it or promoting them, just telling you what they tell me.
My DD also prefers the Mizuno low rise pants. I will also tell you that our team choose to go with plain white and plain navy pants. They are easy to find and my DD has three pairs of each, which makes doing laundry (especially soaking the white pants to get the stains out) much easier to manage. We also avoided pinstripes so we can soak the white pants in Iron Out or OxyClean without worrying about the pinstripe bleeding.
