At least for me. See, you've got to get women shapes (triangles; alot of triangles) down, before you stylize (cartoon) them.
My solution has been to steal liberally. New find, Chris Reccardi:
Also of assistance is Posemaniacs. In a bout of OCD, I clipped and merged into a .pdf a good bit of the female poses (6mb low quality version; the original 156mb file would cost more bandwidth than I'm willing to spend right now). Snag a copy here.
Useful for those times when my internet connection is dodgy; but no substitute for the live site.
