Dare we set up a table of outgrown clothes at the Getaway? Those of us who have reached Size 8 can donate their 10s and 12s; the 10s and 12s can add theuir 14s and 16s and so on up to the preggie stuff.
Everyhting must be clean, pressed and wearable - tough for those of us with large bosoms that catch everything...and for those with colicky babies who cough up all sorts of nastiness on Mom.

A suggestion:
Measure yourself and cut pieces of ribbon to the length - bust, waist and hips. As you lose, cut the ribbons and save the cuttings for a symbolic burning. Or wait until you reach goal and cut to fit. You will have tangible proof of your success.
