Maybe this will help...
If I didn't link that properly, just scroll down on the main Betty Buzz page and look for the kokatat thread (about drysuit sizing) that I started asking just a little while back.
I don't know how different the men's vs women's cuts are, but they make them gender specific for a reason, I suppose. Luckily, it sounds like you can go try them on...I would go that route.
I've heard complaints about the drop seat and I would personally steer clear of that - that would drive me crazy!
Good luck on your search - I AM SO HAPPY I FINALLY GOT A DRYSUIT!!!!! SO. SO. Worth it!!!!
