because I was sick of 'send dress away to be cleaned' remaining unticked on my to do list.
I can report back that it washed well and looks absolutely fine.
Just popped it on a warm wash inside a duvet cover to protect the beading.
I don't appear to have lost any beading and it's almost spotless.
Just thought I'd share in case any one else tempted.
Disclaimer: If it had shrunk, I wouldn't have been too upset, I doubt DS will want to wear it in the future :)
