Laura Bailey first wore this RM by Roland Mouret Osu dress in December to the “British Fashion Awards” in London.

The dress is taken from the designer’s “Rainbow Collection”.

First things first – that hair! What were you thinking???!

Hairstyles such as these are only really acceptable under the age of five and still then it’s questionable.

Laura has committed a major fashion crime by choosing to wear her hair like this, especially with such an amazing dress.

I’m not crazy on the dark black tights against the yellow but London + December = Brrrrrrrr.

Devon Aoki wore this dress just a day later to the “RM By Roland Mouret Rainbow Collection Launch” in LA.

I love the studded clutch that Devon has worn with this dress.

This dress clings to Devon in all the right places and I love that she’s chosen not to wear any accessories – this dress is a statement in itself.

I also feel some major hair envy coming on. I love the way it cascades over her shoulders.

This is a no-brainer. For the disastrous hair alone Laura loses out to Devon.

This dress is available to buy from Net-A-Porter.com.
