A custom, unashamedly sexy, backless mini dress covered in scarlet sequins from Markus Lupfer of course!" Deeley told InStyle.com. "I teamed it with nude Jimmy Choo shoes and nothing else. I just let the dress do the talking!" 03 of 13 Cat Deeley's Striking Onstage Looks Mathieu Young/FOX December 03, 2009: "My style inspiration was Madonna circa her Blonde Ambition tour, but her Jean Paul Gautier is my Alexander Wang!" 04 of 13 Cat Deeley's Striking Onstage Looks Kelsey McNeal/FOX June 24, 2010: "This look was sexy courtesy of Elise Overland," Deeley told us. "Tousled hair was the order of the day. The only accessories needed were a knowing smile and a glint in the eyes." 05 of 13 Cat Deeley's Striking Onstage Looks Adam Rose/FOX August 04, 2011: "The inspiration behind my yellow chiffon River Island maxi dress was Jerry Hall circa Studio 54. OTT? Possibly. Fun? Definitely! From the giant corsage sitting on my collarbone, to the thigh high splits, this dress was a joy to wear!" said Deeley. 06 of 13 Cat Deeley's Striking Onstage Looks Adam Rose/FOX August 03, 2011: "I fell in love with this super girly, pale pink pearl and lace Valentino confection. The detail is so delicate and beautifully done that a girl can't help but swoon." 07 of 13 Cat Deeley's Striking Onstage Looks Kelsey McNeal/FOX July 01, 2009: "This was an homage to Sarah Jessica Parker," said Deeley, who cinched her pretty DVF dress with an edgy belt from Temperley London. "The Sonya Rykiel shoes are over eight years old, but I think they look very Balmain." 08 of 13 Cat Deeley's Striking Onstage Looks Kelsey McNeal/FOX November 10, 2009: "Are there no limits to Roland Mouret's talents? He is the most charismatic, sexy, stylish French man...who creates beautiful designs that make women feel fabulous!" Deeley said. "Team the dress with Givenchy heels, iridescent alien eyes and a punk rock inspired hair style and I believe we have perfection!" 09 of 13 Cat Deeley's Striking Onstage Looks Michael Becker/FOX November 3, 2009: "This was my homage to Carrie from Sex and The City," said Deeley of her Jasmine di Milo dress. "My inspiration was the 'naked dress' that she wore on her first date with Big, only mine got me into a lot less trouble!" 10 of 13 Cat Deeley's Striking Onstage Looks Mathieu Young/FOX July 16, 2009: "I said, 'Think super hero, hippy, space bunny.' So on went the Matthew Williamson sequined sheath dress—with amazing shoulders that even Alexis Carrington Colby would be proud of—and futuristic Sergio Rossi sandals," said Deeley. "Love it or hate it, I dare you not to have an opinion about this look!" 11 of 13 Cat Deeley's Striking Onstage Looks Kelsey McNeal/FOX July 29, 2009: Deeley chose a Balenciaga dress in a hot hue, pairing it with DSquared2 platforms and a chunky Mulberry cuff. 12 of 13 Cat Deeley's Striking Onstage Looks Frank Micelotta/FOX August 04, 2010: "The look was a full Debbie Harry tribute. Think gothic and slightly modern with just a hint of glamor. The dress was from Shareen vintage and the shoes were Givenchy," Cat explained. "I once met Debbie and I have to say, she's one of the coolest chicks I've ever met. She's my number one!" 13 of 13 Cat Deeley's Striking Onstage Looks Douglas Friedman Own an iPad?
