Vogue’s annual “Best Dressed of the year” list is already out, and they took special interest in 2011’s best-dressed sister acts. You’d think that with the way everyone is falling all over themselves for the Middleton sisters, that those girls would have gotten top honors. You would be mistaken. First of all, Pippa and Kate would NEVER pose for a supplemental issue of Vogue US. Well, Pippa would love to, I’m sure, and Kate might even want to as well, but she’s not going to right now. Anyway, Mary-Kate and Ashley Olsen, they of the oversized boho looks and the $500 white button-down blouses took the cover.

You can see the list of “best dressed sisters” here at Vogue. Some of the ladies definitely deserve to be on the list, although I wince every time Elle Fanning is mentioned in a major fashion context. She’s 13 years old, and she’s being put out there like she’s some major fashionista. That bugs me.

The list also includes Beyonce and Solange Knowles (ha) and the Middletons of course. Pippa and Kate are given credit for popularizing the mid-thigh skirt or dress. Mark Holgate, Vogue Fashion News Director and Editor of the special issue, told Reuters: “It’s short enough to be impossible for an older-generation royal to wear, long enough to be decent when sitting or bending down to talk to a child.”

About the Olsens, Holgate said, “Are there any more chic, stylish, cool, and original sisters than Mary Kate and Ashley Olsen? They are incredibly stylish…They get it right a lot of the time and then sometimes they don’t get it right. That’s actually great because it shows that it’s their hands reaching into their wardrobes. They don’t have someone telling them, ‘This is cool, this is hot, this is what you should be wearing.’ It comes from within them. It’s instinctual. Look at what they’ve done with (their fashion labels) The Row and Elizabeth and James. They are legitimate fashion forces.” MEH. Beautiful pics, though.
