Not the OP but at our FCPS school, exposed midriffs are forbidden. My kids were taught to raise their arms to make sure the shirts don't rise above the waistline. If OP's DD's tops are riding up, it sounds like they're not long enough to begin with.
And, I second the suggestion to get leggins/pants from Target/Old Navy. My DD go the occasional hole but a quick stitch was sufficient to get a lot more uses out of them.
