The fact that neither of you has enough sonic autism to know that you're both right is saddening. All of pic related are from SA2's marketing and in-game assets. There were two designs for her: a non-backless dress with a huge chest that was used in the 3d render and in-game multiplayer mode, and a much flatter (though not completely flat) variant with a backless dress that was used in the official character art and in the game's story mode.

I remember, way back when I played the game, wondering why there was such a difference between her two character models depending on what mode you were in.

Notably, SA1 gave her a backless dress and a big chest, and Sonic Shuffle gave her a backless dress and a flat chest.

Other media usually went with a backless dress and a modest chest, most closely matching what was used in SA2's story mode.

>tl;dr SEGA has been inconsistent about Amy's chest size all along
