The love affair between The X Factor and the great British high street continued last night as Ella Henderson accompanied her mentor Tulisa to the Cosmopolitan Ultimate Woman of the Year awards in London.

Ella wore a pretty white jacquard and lace prom dress from River Island which is available online now for £85. She teamed the dress with black tights, which are becoming a bit of an Ella trademark (appparently she doesn't like showing her legs, though we have no idea why) and Topshop 'Shackled' embellished platform shoes - yours for £68.

Tulisa, on the other hand, did get her legs out, in a bright yellow ruched mini with beaded strips of metallic trim and a sheer halter panel, with Terry Dehavilland 'Amber' shoes (£450) and a silver clutch with a butterfly clasp by Aruna Seth (£495).
