Mary-kate Olsen not Ashley Olsen

Like so many of you, dear readers, almost every member of the WhoWhatWear.com staff could be considered a sunglasses aficionado. We always welcome any opportunity to tweak our collections, so you can imagine the office-wide delight when we spot a new must-have style on the horizon. After the S/S 10 shows, we had more than a serious hunch about what the season's key accessory would be—cat-eye sunglasses, of course!—as everyone from Alexander Wang to Miuccia Prada showed their own interpretations of feline frames. But we're not the only ones who think these shades are the cat's meow: tastemakers like Diane ...

Mary-Kate Olsen is at it again pairing a fancy pair of pointy ankle boots with an uber casual oversized plaid shit and jacket. We're not sure if this is a case of trying too hard... Or not trying hard enough. Related Links: Good Morning Olsen Twins

Mary-Kate Olsen didn't let Friday's 70-something degree weather in NYC affect her clothing choices - she left her apartment in layers and what's becoming both her and Ashley's trademark oversized scarf look . She's home in New York while her costars in Beastly , Vanessa Hudgens and Neil Patrick Harris, kick off their promotional tour with a stop at ShoWest in Las Vegas . The film isn't out until July, so there are sure to be more chances for Mary-Kate to show off her unique fashion sense at other events with Vanessa and NPH. View 3 Photos ›

Mary-Kate Olsen’s style has been hit or miss over the years, but I totally dig this city-smart look. Of course, I am a sucker for a Proenza Schouler PS1 handbag, such as the black one MK’s toting here along with a bulkier unidentifiable tote. And I love that flash of red from her vibrant scarf — it’s agreat way to break up the black. I’d say this is a hit. Photo from People.com.

A large hat, over-sized sunnies and lots of layers kind of makes for a top heavy look on Mary-Kate Olsen, if you'll pardon the pun. I really like the menswear appeal of this entire look, but with Alice in Wonderland premiering this week she's just begging for a mad-hatter comparison. What do you think? Stylish or stupid? Do you like Mary-Kate's topper?

Josh Hartnett had his new puppy for company on Saturday as he went through security at LAX. We had a peek at Josh's furry friend in January, and the little guy has grown in the past two months. Josh has been earning his fair share of frequent-flier points in the meantime, as he crisscrosses the globe to attend fashion shows and joke around with Jimmy Kimmel . All the travel hasn't affected his love life, evidently, since he was recently linked to the freshly single Mary-Kate Olsen after their time together at the BAFTAs . View 2 Photos ›

New York fashion week took place recently, kicking off fashion weeks around the world. One show in particular - Proenza Schouler - was the show to be seen at, with Nicole Richie, Mary-Kate Olsen and many more celebrities gracing the front row. After all the (well deserved) fuss that was made over their spring 2010 show, everyone was eager to see what was produced for the fall collection.
