She's fat, but the dress fits. I would stick a bigger bonnet on her to balance it out, and I can see some people down on the shoes (the battle over acceptable mary janes never seems to end in this fashion). It's also a little wrinkly, but cotton is far less forgiving than polyester when it comes to wrinkles, so I don't see it as a big deal.
>It looks like it was made out of a curtain
At times, it's hard not to resemble a tablecloth or a fancy curtain or a sofa in this fashion, so I don't see that as a particularly egregious sin. No, it's not the best quality fabric, but I see gulls throw themselves at tissue-paper-polyester brand and indie dresses all the time.
tl;dr as >>10822018 said, it's literally fine.
