Kylie Minogue, Denise Richards & Katharine McPhee

Cheryl Hines, Taylor Swift & Carrie Underwood
Good things come in threes, at least when it comes to the revival of this sequined BCBG dress on the red carpet over the past couple of years. But who's your favorite star sparkler?
(If Taylor's your fave, sound off in the comments!)
Denise Richards & Lisa Rinna
The celeb pals and smooch buddies are so tight they've started dressing alike—stepping out within days of each other in a purple Halston Heritage dress. It's so pretty, who can blame them?
Blake Lively & Alexa Chung
The Gossip Girl star wore it first, but when it comes to this busy Chanel dress with sheer lace midsection, could anyone really wear it well?
Salma Hayek & Rebecca Hall
Hayek's a doll, but she just doesn't have the height to carry off this leggy romper look. Then again, even Hall looks ridiculous in this YSL jumpsuit.
Bar Refaeli & Victoria Beckham
Both ladies step out in Roberto Cavalli, but we're not sure this dragon queen dress deserved one outing, let alone two.
Katy Perry, Salma Hayek & Kim Kardashian
Three wunderbar stars. One sexy look. Which busty babe pulls off the Bavarian beer wench costume best?
(If Salma's your fave, sound off in the comments!)
Jada Pinkett Smith & Rihanna
Who's queen of the animal-print jungle in this long-sleeved Pucci mini? You decide!

Lily Allen & Kate Hudson
It's a fashion duel as these two stars face off in matching Louis Vuitton capes!
Mary J. Blige & Drew Barrymore
Hollywood's got a thing for glitter—as you can tell by this double outing of Catherine Malandrino's gold brocade dress. Twice as nice, we say!

Cat Deeley & Natalie Portman
Who wore it better? Who cares! It's time for both Cat and Nat to retire this messy Lanvin look.
Rihanna & Jennifer Garner
Both ladies look fab in this Stella McCartney frock, so it comes down to a match of the manes: cropped 'n' colorful or loose and wavy?
Lil' Kim, Naya Rivera & Carmen Electra
Three's a crowd as Hervé Léger's blue bandage dress gets used and abused on the red carpet this summer.
Brandy vs. Michelle Obama
It's Moesha versus Mo'bama as the women compete in virtually identical polka-dot dresses by designer Kevan Hall.
Ashley Greene vs. Blake Lively
Both actresses look fab in Antonio Berardi's lingerie-on-display dresses. But whose peep show are you picking?
Katy Perry vs. Serena Williams
Catfight! The singer and the tennis pro face off over Dolce & Gabbana's leopard-print frock. Meow!
