The most effective way to do it, is to do it.

I have both the KISS and YPRO shorts. The KISS chamois is okay, but the YPRO is much better for longer rides. I always swore by them, esp, since Castelli's sizes can accommodate smaller pelvises (er, pelvi?).
HOWEVER... ever since I purchased a pair of Specialized BG Pro womens shorts, I won't wear anything else. Specialized makes three levels of shorts and their Pro is the top of the line. Their inseam is a bit shorter than most, and they're a bit pricey ($150) but my girly bits think they're worth every penny. Plus, they come in XS.
P.S. Specialized's jersey line is not nearly so special. I still prefer Castelli on top.
I find that in shorts Castelli and PI are similar in sizing. Not so in their jerseys. I have to go up a size in Castelli jerseys.
For Assos, well . . . . well . . . in the lady half shorts and lycra knickers go up one size over Castelli and PI. If you are looking at the Roubaix knickers/tights (fondly known as the Splitter), forgitaboutit. A size XL might fit a 2 year old.![]()
