Who? Katy Perry and Selena Gomez
What? Katy added a dash of vintage Hollywood and a pinch of vamp to the Unicef Snowflake Ball. The singer wowed in a Naeem Khan dress, complete with shall, and a pair Guiseppe Zanotti shoes - although her sparkling flower-detail gown was so long you couldn't see them... she could have been wearing Crocs (bleugh) for all we know.
Actress and Justin Bieber's on-again-off-again-on-again girlfriend Selena also took a walk on the gothic side in an equally glamourous Dolce & Gabbana floor-length dress.
Verdict? Katy's dress has caused a style rift within Team MyDaily (perhaps we were just put off by Katy's rabbit in the headlights facial expression), whereas Selena's take on glitzy goth has us wanting to slip into that slinky D&G number ourselves.
