HELP! How can I look like Adele?

[4MinWarning]

Hello everyone :)

So basically, I'm going to a fancy dress party and of course i'm going as the beautiful Adele.

I've been looking for the iconic Adele black fitted dress with the band at the waist - you know the one, but I can't find one anywhere. They're all too night clubby, trashy looking. None that Adele would wear.

Can anyone help me out? Does anyone know where I can buy this dress?

Thanks lovelies :)
