Mr and Mrs. Foglio prefers to draw their ladies with some generous curves. 3/4 realism makes for some very attractive characters on both sides of the gender split. If I met a lady like Agatha in real life I think I would be confused as to how she walks without those calves smashing into each other.
On that note: I can't remember if Kaja or Phil actually draws the comic.
P.S. I approve of this Girl Genius reference.
