There were a few others in the comics, like Hershey the cat, and Barby Koala. (Kinda makes it odd, Sally was the only one whom got hate for that.) Julie-Su also lacks pants.
I also remember a few background SatA.M. cartoon female characters like that too.
There aren't any game females like that. (Though, in "Sonic Forces" there are some fur patterns that can make your female Avatar look naked, but granted, they lack curves, and it could be considered a bodysuit.)
