Dry clean your dress, put it in an acid free box with moth balls, keep it away from extreme heat or damp, and that is it. Do not pay 130 dollars for a box with a clear window in it for their "preservation" process. It is literally dry cleaning and that's it. Its not worth the cost just to have it folded and facing the window! Don't let them tell you about "acid free boxes" or any of that nonsense for 130$. A lot of stores sell garment storage boxes with acid free tissue for 30 bucks. Dont do it!! Unless of course you want the box with the plastic window in the front.
