Gown Preservation

Have any of you girls had your gown cleaned or preserved? Mine is still hanging in the bag at my Mom and Dad's house and I am thinking that I should get it cleaned.

The only problem is, I don't want it preserved in some air tight box that I am not allowed to open. I want to be able to look at it and maybe, if the mood strikes me, put the s u c k e r on again!

Any advice or recommendations for cleaners?
