Oh Pesty. I'm so sorry that your eagerly-looked-forward-to dress is such a disappointment.
It's lovely that you're so much smaller than you were - and you need to take some comfort from that - but obviously that doesn't help when it means you can't look as stunning in the dress as you deserve to after all your hard work.
I really hope the seamstress can help.
Do you have a Plan B at all? I know it's devastating that Plan A might not be the amazing success that you planned, but I hope it won't totally spoil the evening that you'd been looking forward to so much.
Please don't ruin everything you've done by letting your wagon wobble last. You're worth so much more than that.
Big, big hugs...
