OKay so who does ballet?

Okay so I love ballet soo much it looks beautiful! But it must take hard work and strength. I used to do it when I was little and I was good, but my mom pulled me out because i didn't really like it at the time. I really want to do it now, but I don't remember anything and have gotten very chubby. Do you have to be skinny to do ballet? I feel clumsy while doing moves (I went to a university dance workshop but I'm just done grade eleven) I feel like its too late to start again! Is it possible to be to fat to dance? Cause I love the look and I want to do it so bad, and every video I see they say pursue your dream and you'lll acommplish it.. I just don't want to look stupid, I'm pretty self concious! Any tips??
