I just found the BEST site for free design croquis. Lots of different body types, including children, babies, boys, men and of course women. Check out Designer Nexus for a variety of croquis. You're welcome! (I'm bummed ... I just bought some croqui templates!!)
Croquis are templates used for fashion design and fashion illustration. (They also have a whole section of just flats!!) Love this website.
