What and what not to wear... by Liz Hurley, Jordan and Trinny

Trinny Woodall may be the professional adviser on style but last night at a charity event, all the fashion tips were coming from the evergreen Liz Hurley.

The 42-year-old model wore a low-cut babydoll dress last night as she joined the What Not To Wear TV presenter at a gig hosted by The Who's Roger Daltrey at the Old Billingsgate fish market in London.

But it was the outfit of a certain glamour model turned author that stunk the most, definitely more Jordan than Katie Price. Let's hope Trinny had a quiet word.

Liz showed more flesh, with cleavage and legs proudly on display in a Grecian-style minidress, while Jordan just got it all wrong with her skin-tight lycra catsuit, accessorised her Avengers-style ensemble with a gold belt, gold shoes and bronzed husband Peter Andre.

The event was a gig by RD Crusaders, a band fronted by one of the all-time hellraisers which raises money for a number of charities.

Trinny, dressed in a high-necked blue number, leant a supportive arm to a tired-looking Liz - who failed to crack a smile all night - as they left the fundraiser.

Fresh from her work experience at Selfridges Department Store in London, Princess Beatrice joined her mother Sarah Ferguson, Duchess of York for a family night out.

Contrasting chintz with glamour, the 20-year-old royal teamed a a poufy, floral gown with silver sequinned shoes, while her mother played it safe in a black shift dress.

Mark Ronson, who attended with new girlfriend, model Daisy Lowe and jazz singer Elkie Brooks were amongst the performers who shared the stage with organiser, The Who singer Daltrey.

The star-studded evening started with a champagne reception followed by a lavish meal from the owner of The Ivy restaurant and raised thousands of pounds for cancer charities.

Other guests included Tamara Beckwith, Sir Philip Green, Tania Bryer, Vanessa Feltz and interior designer Kelly Hoppen with her boyfriend Nicky Clarke.
