Awww..well, if you want a slice of hope, I may have some for you. Seeing as how you started with a fine set then you can in fact look forward to a reasonable return to glory. Like you, my wife suffered the same sub par perkiness but they came back and even now, at 50, her boobs are half that age.
In the meantime, enjoy your party and I would love an explanation of what exactly a debutant ball is.
