can't fix it!!

hmmmm, for some reason I can't edit my side bar anymore. Where my wips show.... what the hell happened, and how do i fix it! A few of those things are done, and a few more have been started. :)

Knitting question

I have a question. Not too sure if it's feasible or not, but I knitted a sweater for my eldest daughter years ago. My youngest now fits into it and really likes it, but the ribbed band at the waist has no shape anymore.

Is there a way to fix this?
This piece was worked from the ribbed waist, up.



It's not the best pic, but it shows that there is no shape in this piece. Any help / advise at all would be greatly appreciated!
