Katie Price's cage fighter boyfriend wore her sexy clothes to a book signing yesterday (21.10.09).

Alex Reid - who recently revealed he enjoyed dressing as a woman - donned the infamous flash-flashing gold leotard Katie wore while partying in Ibiza earlier this year, heavy make-up and a long dark wig to the launch of Katie's new tome 'Standing Out: My Look, My Style, My Life' in London.

Alex was joined by Katie's horse trainer Andy Gould, her brother Daniel Price and stylist Phil Turner, who were all wearing replicas of outfits Katie has worn in the past.

To stand out from the boys, the glamour model - also known as Jordan - wore a large blonde wig and a tight red gown complete with feathers, ribbons, sequins and a long train.

In the book, Katie reveals the details of her extensive clothing collection and gives her own tips for women - or men - who want to look like her.

One pearl of wisdom reads: "You don't need to spend a lot of money to look cheap but remember, even though you might be dressed like a cheap tart, it doesn't mean you have to act like one."

When it comes to packing for holidays, Katie says: "For a week-long trip, I'll take seven daytime outfits for hot weather, seven daytime outfits for not-so-hot weather, seven beach outfits and seven night-time outfits. That's 28 plus underwear, shoes, earrings, bracelets, hairclips and bags."
