Fancy diaper covers...

Maybe this is a silly question, but has anyone use those fancy diaper covers AFTER their daughter is potty trained? Would it look weird to put them over underwear under a dress?

I was just cleaning out my daughter's dresser drawers and noticed we have a few of those left over and that thought just crossed my mind.

Thanks!

If I have a cover that matches Gwen's skirt or dress and it still fits her, I use it! Gwen isn't exactly lady-like when she's playing, so I figure it's better than her flashing everyone with her underpants.
