Well, depending on what you love about it, you could do a lot of things. If you love the fabric, cut it up and cover some throw pillows with it. Or make a pretty blanket. Or small table cloth. Or cloth napkins.
If you love that it is long and swishy, maybe cut the back out and make it into an apron and feel fancy in the kitchen!
Or you can applique some pretty felt flowers to change the look a little and still wear it. Or dye it. Or better yet, tie dye it if your tastes run that way.
I have the same problem that I still love clothes that I never wear anymore, so I have thought a lot about this!
