I'm off to a party in two days. My frock, which I hadn't tried on until now, is gaping at the back and won't fasten. I've got the perfect shrug to go with the dress, and it covers the zip problem, especially if I use a well-hidden safety pin to secure it at the base of the gape.
I also have another dress, which has no problems zipping up but isn't quite what I want to wear to the party.
What should I do? The dress I want to wear is in my size, but has no 'give' in the waistband.
