Unfortunately for bigger people costumes often need to be more complicated and better-made to give enough support and look good. For example, supportive undergarments, especially corsets, really help smooth things out and give a nice line. Mind you I think everybody should put boning in their bodices, whether large or not, but bigger people need to use sturdier fabrics and steel boning. I learned that the hard way when making a corset for a friend of mine - it needed a lot more support and reinforcement than I was used to.
It *is* possible to be a larger person and still look great in costumes - it just usually takes more effort. And I agree 100% with the above comments that people need to evaluate what costumes will look good on them and make any modifications in order to make costumes more flattering. ^_^
