Thanks all, as usual you give honest opinions! The reason I asked the question, is that I have a horror of people thinking I'm trying to be 18 again (shudder!), and looking age inappropriate.
So, this is still on the list, but, I've been sidetracked by The Amelia Tea Dress, which I love. It may go on the 'I'll make this for Christmas' list (we go away), and would probably look OK on holiday.
Now, back to the job in hand, The Amelia Tea Dress!
