January Jones joined a host of stars on the red carpet for the Metropolitan Opera Gala Premiere of Jules Massenet’s ‘Manon’ in New York City last night.

We struggled to get on board with January’s recent red-carpet choices, but on this occasion she picked a great look.

Whilst this YSL Fall 2012 dress may not be that exciting at the front, the party is most definitely at the back as the dress reveals a thigh-high split and an open back.

Pre Angelina Jolie’s leg, I think January would’ve made more of the split from the front, but we live in a ‘post Angelina Jolie’s leg’ world where one is ridiculed for appearing to try too hard.

As January’s drape-neck dress has a light embellished detail going across it, she kept her jewels to a minimum by just adding studded diamond earrings.

Retro loose waves, a coral lip colour and a purple eyeshadow completed her look.

Love or loathe?
