You Had A Bad Day

At the "Serious Moonlight" movie premiere on December 3, 2009, Meg Ryan wore a long-sleeve, full-length floral dress that reminded us of an Oriental rug. The star usually looks effortlessly gorgeous in simpler, chicer attire, as seen here (right) at another event.

In sweats and white running shoes no one would believe Katie Holmes is considered to be a style icon. By keeping a simple gray top and a scarf, but ditching the disastrous bottom half of the outfit, Holmes looks fashion forward but not over dressed.

Drew Barrymore's plaid frock and combat boots ensemble (right) is a throwback to the grunge-filled '90s. It's not necessary date night attire (she is out on the town with on-again-off-again-on-again beau Justin Long). On a different day, the actress rocks flannel in true hipster fashion with a cropped leather jacket, an Iron Maiden tee, and lace-up knee high boots. (Bonus points to you Ms. Barrymore for matching your sunglasses to your belt!)

An oversized hoodie and Uggs can't conceal the fierceness that is known as Beyonce. The pop singer landed at JFK International Airport in New York City with her entourage of bodyguards dressed like a college freshman. But on a brighter day, she touches down dressed in head-to-toe black including trendy sunglasses to block the camera's flash.

The 42-year-old singer wore this Ugly Betty meets Fat Albert inspired ensemble out to lunch with a friend. Now we know your friends are supposed to love you unconditionally, but even a BFF would be within their rights to be slightly embarrassed dinning out with someone in this outfit! On a much better day Janet Jackson proves she knows how to work a classic L.B.D. to create a chic low maintenance look.

Sure, everyone loves to wrap up in a warm comforter, but the Grey's Anatomy's starlet looks took that cozy concept to the next leaving, wearing a top that resembles a blankie with sleeves. On a better day, Katherine Heigl's tunic and boots combo proves that style and comfort can go together.

Menswear is hot this season, but that doesn't mean you can mix any old item you find in your BF's closet into your wardrobe. This XL hoodie and long skirt combination looks just plain lazy and adds major pounds to Jessica Simpson's petite 5 foot 3 inch frame. Simpson shows she can do menswear the right way, rocking a double breasted blazer with tailored jeans.

Sky-high stilettos are not meant to be paired with a baseball hat, Eva Longoria, not on the red carpet and not even when you're running errands. As the Desperate Housewife clearly knows, a plain button down paired with skinny jeans and flats is the fashion forward way to race around town.

Mary-Kate Olsen is eccentric and we respect that, but if she must wear something that resembles a yak pelt, the least she can do is pair it with slim leggings and stylish boots, rather than denim cut-offs and Converse.

In essence both these looks are comprised of a ponytail, a tank top and a casual pant, but swapping baggy sweats for a flattering pair of jeans takes Hilary Duff's look from a sloppy don't to a classic fashion do.
