I'm not even sure how in the hell she thought it was tafetta. If I can find the fabric, I think I'll fix it myself and redo the whole top. It's wrong anyways. Here's an image to show you what I mean:

It's a really low cut top with kind of a lace on it. Any suggestions for that?
She's not a normal commissioner. I asked her to do the dress. Honestly, the other dress that I had seen her make and the quality and everything, doesn't match what she made here. I know she makes her own costumes, but you would never have guessed that she had made my dress. If I can get Jessica into her dress I'll show you what hers looks like. From what her mom is saying, it's worse. I won't let anyone get near her costuming . . . if someone tells me they're doing one from her . . . I'll hiss at them.
As for the repairs I now plan on doing to this costume, How do you gather exactly? I've seen something where it says to run the longest stitching that your sewing machine allows through the fabric and then pull on it and that gathers it . . . is that right? I've tries gathering like that before and it didn't work.
