Can i customize my gta online character model?

The only verified source supplied is a Wikipedia entry about Red Dead Redemption, which describes its setting, plot, and themes but does not mention GTA Online or any character customization options for that title. Because there is no evidence presented that addresses the question about customizing a GTA Online character model, we cannot confirm whether such customization is possible or not. Users seeking this information should consult official Rockstar Games resources or reputable gaming guides that cover GTA Online features.
