Oddly enough, a grade skip seems to have helped my DD7 fit in better. It fixed the "bored and miserable" problem (at least for this year), and because it took a while for her to adjust to the 3rd grade academics, she started the year looking "normal smart" and not "weird smart." Her first-grade friends last year had all been kind of socially and academically marginal kids, but her 3rd grade friends are mostly optimally-gifted popular kids.
I was another one whose mother sewed her clothes, and didn't buy me bras, and told me that caring what other people thought was a waste of time. We've really gone the opposite way with DD - I've got a high tolerance for trendy clothing and high-value playdates and high-status gadgets. She took her set of Amulet novels to school earlier this week, and had a whole rotation of borrowers set up - her teacher commented she was the most popular kid in the class because everyone wanted to borrow her books.
