This is the end – the very end – of our Rihanna for River Island giveaways, and it’s a doozy! Tuesday’s black maxi dress in the cream colourway, for one of you lucky Fash Mob readers to get your mitts on – and as we’re heading into the weekend, this competition is going to be open for a whole two days.

The dress is a UK size 12, and all you have to do to be in with a chance of winning one is share this post via Twitter or Facebook (and it helps if you like Fash Mob on Facebook!) – and leave a comment below! Remember, share and comment!

This competition will close at midnight on Sunday, March 10th. The competition is open to Republic of Ireland residents only. No correspondence will be entered into.
