Mel B has the X factor in GILES

Mel B looked beautiful wearing a GILES gown for the grande finale of this year's X Factor. The singer chose a floorlength white silk look from the A/W 12 collection for Sunday's TV show, which was watched by 10million people.

This isn't the first time GILES has dressed a Spice Girl. Victoria Beckham famously wore a bespoke black bodice dress for the band's performance at the 2012 Olympics closing ceremony.

Clearly these ladies know who to call for a big occasion.
