Yeah, I toss it at my DH and ask him to put new elastic in it. Just need an elastic threader, some elastic and a little bit of spare time. Least stressful way of the lot. I've tried everything else and it is the only one that I will promise won't send you completely crazy by 6pm.

But you are welcome to join me in an evil email campaign to the producers on how ridiculous they make the waist sizes! =)
