Model meshing glitch

Here, Luigi's model has been "mixed" with Peach's due to the model meshing glitch, and it appears as if Luigi is wearing Peach's dress.

The model meshing glitch, also known as the dress glitch, is a glitch in Super Smash Bros. Brawl where two characters appear in the same position in the match results screen. If executed properly, the two character models should be overlapping each other, looking as if they were forced together, hence the term "mesh" in the glitch.
