(click on the images above for price and store information) WHAT: Boyfriends beware! This season your girls will be making another shopping trip to your closet - this time in search of a chunky watch or herringbone blazer. Inspired by the Fall 2009 runways of Chloe, Hermes and Isabel Marant, everything is loose, baggy and inspired by the boys! From voluminous harem pants (our personal favorite of the season) to oversized blazers, the look is androgynous and sexy all at the same time. WHO: Celebs like Sienna Miller, Diane Kruger and Liya Kebede have been rocking the harem/peg leg pant in all its voluminous glory all summer long while the boyfriend blazer has long been a friend of every fashionable celeb including Rachel Bilson, the Olsen twins, Kirsten Dunst, Kate Moss...the list goes on and on! BEST BUY: BB Dakota's double breasted boyfriend blazer is a steal at $98. Its borrowed-from-the-boys herringbone texture and black half collar make it the ultimate topper for fall. TIP: Harem and peg leg pants may seem scary at first (you'll get quite a few stares from the less fashionably inclined), but the key is finding the right hem length. Remember that you want to show a bit of ankle so don't get buy them too long (or if need be, simply get them hemmed to the right length). Also they look most flattering with heels or heeled booties so leave the flats at home on this one.
