• Like most sisters, Mary-Kate and Ashley Olsen swap closets, trading one oversized ensemble for the next. But Elizabeth Olsen would be hard pressed to squeeze into her older sisters' duds. The youngest Olsen stands a full head above her famous siblings, and prefers tailored, polished pieces on the red carpet. It's the classic battle of uptown classicism and dowtown chic, but this time over the dinner table.

  • You either find the Middletons to be extremely fascinating (ahem, Barbara Walters) or two sticks of boring with great hair on top. While Pippa dresses her butt-of-the-Gods in conservative and demure styles similar to Kate, the younger Middleton doesn't have a Queen fingering through her wardrobe. Pippa opts for knee-high boots over kitten heels (the horror!) and the occasional plunging neckline instead of collars and cardigans.

  • If you can tell Elle and Dakota Fanning apart, you can answer the question of who has better style. Both porcelain blondes favor neutral palettes from designers like Valentino who are heavy on ladylike frocks and lace galore. The effect? Either the look of sophisticated elegance or a ghostly washout.

  • Sienna and Savannah Miller are so stylish that they launched their own highly acclaimed fashion line, Twenty8Twelve, in 2007. The former Vogue cover girl favorites signature English style (sometimes polished, sometimes funky, always fashion-forward) while her fashion designer sister sports menswear pieces like a pro and rocks clean, tailored staples.

  • How could Theodora and Alexandra have avoided rock star style with a dad like Keith Richards? The model siblings always drape their sleek frames in of-the-moment fashion, from fringed accessories to faded denim and tailored jackets. Which leggy blonde pulls off the look of urban glamour best?

  • While Jessica Simpson, a near-billionaire fashion mogul in her own right, does her southern roots proud with flouncy dresses and hats fit for the Kentucky Derby, younger sister Ashlee struts edgy cropped do's and bohemian outfits.

  • The two Disney starlets can be spotted hand-in-hand on red carpets and L.A. sidewalks alike, but their styles are far less compatible. Hilary opts for fitted minis and glam sequins, while Hailey prefers laid-back, colorful cool.

  • Paris Hilton isn't exactly synonymous with clothing, but her handbag-designing sister, Nicky, is an exemplar of California dressing. If Paris could spend her life in a Tinkerbell costume we're pretty sure she would (girl doesn't stop with the glitter and gowns) but Nicky's chic minimalist style more than makes up for her sister's faux pas.

  • Reality TV's first family shares a pension for animal print, fitted pencil skirts, and sky high Louboutins... which were all considered things of class before these ladies got their hands on them. While Khloe continues to dress for her two sisters' body types, Kim should buy stock in Herve Leger, and Kourtney needs to spend less time (and money) on her own wardrobe and start worrying about her boyfriend's.

  • If sibling similarities could be determined by style alone, we'd be calling for a Beyonce-Solange DNA test. Mrs. Jay-Z keeps her diva reputation strong as steel with couture gowns and over-the-top street style, but her younger sister expertly pairs urban prints and chic sportswear. If you need more evidence of the Knowles sisters' aesthetic differences, consider this: while Beyonce was leading the hair extension trend, Solange went all Britney on us and shaved her head!
