Congrats, I've accidentally bought shoes too ("But mom, they'll fit you too!).
Right now those Marc Jacobs sparkly ballet flats, but in gold. I may be going to prom again because a few of my friends are graduating and they wanna go, so I may be my guy friend's date, and the dress I'm eyeing is dark green satin, so I think those shoes would be perfect. Only thing is my mom doesn't wanna spend the money on them. But I'm hoping my money from my job will cover at least 1/2, 'cause I know she'll wear them too.
