From the Upper East Side to the streets of Hollywood, this Alice + Olivia Jessica T-back dress ($198) is show-stopping on runways and subways.  We’re all looking for that piece that can do double-duty, and this one can go from sassy to (almost) subdued with a simple sweater.

If it looks familiar, it’s because you just saw Little J pairing it with an over-sized cardigan and a multi-chain necklace on the set of Gossip Girl. We’ve all got that easy black coverup, but try this Rich In Friendship necklace ($78) to complete the look.

Loose the sweater when the sun goes down and you’re cocktail ready, like AnnaLynne McCord in Christian Louboutin Engine Spike Patent Pumps. Her’s are sold out, but we found a pair we like even better in these J-Lissmo T-back sling-backs ($795).

You know you loved Lauren’s Mason scoop neck dress from the “Vine” episode of Melrose Place. It’s the one she wore when she got busted in the hotel while working her new side job. We found one just like it from the celebrated Alice + Olivia: the Trina Tunic in Iridescent Sequin.

Why is this style worth stealing? When you polish it up like Lauren did with grey Aldo pumps, heart shaped studs and hammered silver bracelets, you create a sassy socialite look that allows you to do more than steal the scene… you steal the show!

We’re so busy we can hardly keep up with ourselves much less the Kardashians. Kim however, in this gray Alice +Olivia dress, out promoting her new movie Disaster Movie in New York is something we’ll gladly stop to look at.

We must say she looks impossibly chic while showing us how to step into fall in style. Pair a stylish dress such as this that has great versatility with a great pair of shoes to fit your mood, in Kim’s case some gladiators, and you have the look down.

Come back tomorrow for another great celebrity look!

If you’re anything like us E!’s The Girl’s Next Door is one of your guilty pleasures. In that case we’re almost certain you’re going to check out The House Bunny in theaters today where you can catch a glimpse of the lovely lady seen above.

Katherine McPhee sports a classy look to promote the movie on Monday in an Alice + Olivia blouse and wide-leg trousers. We love that she choose this blouse with the flower sleeves making the look more frills and less buttoned-up. Clearly, given her movie role and punchy upbeat music she is a gal who likes to have fun!

Come back next week for more great celebrity looks!

Actress Brittany Snow works the red carpet in a bright orange Alice+Olivia dress and gold heels at the Stride Gum party at Crown Bar. I love the textured detail on the bib of the dress and the ribbon sash around her waist which adds flair to an otherwise basic sleeveless dress. Take a cue from Brittany and have fun with color. After all this is the season to do it before we go back to black!

Enjoy the holiday and come back next week for more of the Look of the Day!
