Grammy Awards 2012: best & worst dresses from Katy Perry, Rihanna, Adele and more

Now you've seen the Grammy Award 2012 winners, let's have a look at who scored on the fashion front. We're pretty sure all the girls bought their dresses from the same shop - one of those ones that specialise in prom attire so embellished in crystals they can double up as sand paper. All of them apart from Nicki Minaj and Rihanna anyway, who seemed to have headed for the 'vicars and tarts' aisle of their local fancy dress shop before getting a little distracted. Nothing wrong with a bit of side-boob on the red carpet so long as you go floor length, Rihanna, don't you worry. That girl who goes out with that tool from Maroon 5, on the other hand... She wore half a dress on the red carpet and we still don't know her name. Was it worth it?

Elsewhere, Jessie J was dressed as a disco ball, Kate Beckinsale almost showed her 'pharaoh's tomb', Katy Perry continued promoting Smurfs 8 months on, Lykke Li worked the David  Beckham look, Fergie was the only one that was sort of interesting in a non-fancy dress way and Robyn wore Buffalo-style boots.
