Who? The Spice Girls.
What? Trying to outshine each other (well, it was mainly Geri Halliwell doing that), as they hit the red carpet together at the world premiere of the new musical based on their songs, Viva Forever *overheats with excitement*.
And how did the looks rate? Geri tried to steal the other girls' thunder in an enormous ice-blue princess dress:
Posh worked the other end of the scale in androgynous chic, consisting of Isabel Marant trousers and a white shirt from her spring 2013 collection:
Emma Bunton was pretty-pretty in electric-blue lace:
Mel C showed off her myriad of tattoos in a fun and flirty khaki mini; and Mel B showed off a myriad of flesh (no change there, then) in a striking sequin-covered gown with a high split:
Where? Picadilly Theatre, London, 11 December.
Verdict? Mel B and Emma Bunton probably struck the right balance of glamour; Geri went way overboard and Posh was too understated (read: boring).
Who do you think looked the best? Let us know below, and see all the pics from the Viva Forever premiere here:
