Here is a better shot of Wonder Girl with Superboy, Beast Boy, and Blue Beetle taken from character stills of a recent Cartoon Network online-game.
Wow - just noticed that they styled WG as an inverse of Superboy -- look at the places where one is covered up but the other has skin exposed. He wears combat boots; she has cropped pants leaving the skin exposed where boots would be. She wears bracelets; his three-quarter length sleeves leave the corresponding skin on his arm exposed. Etc.
