Beyoncé Beyoncé may seem like she has every right to be the ultimate diva, but apparently it's really not the case. In fact, it turns out that the mega-star is just as awesome and polite as we wished she'd be. Designer Rubin Singer-who recently designed a custom unitard which took two weeks to make for Bey's Las Vegas concert on New Year's Eve-told Glamour that Beyoncé, along with sister Solange Knowles, are "the only celebrities that always dry clean and send clothes back in a box, with a hand-written thank you note. They are true ladies."

For someone as rich and famous as Knowles, it's nice to see that she's still got a head on her shoulders-and isn't jaded by her blinding success.
"When you do a fitting with her, she doesn't keep you waiting half a day like some celebrities do," Singer said, adding: "When she's there, she's present and honest and

BEImagesWe're blinded by Jessica Chastain's beautiful bling! Last night, the Zero Dark Thirty star attended the the New York Film Critics Circle Awards in a lace Oscar de la Renta dress and accessorized with a collar necklace by Harry Winston, a massive, stunning piece worth more than $1 million. (Feel free to stare at the huge picture). The experts at Harry Winston tell InStyle.com that the platinum necklace is the jeweler's Queen of Lace design, which features nearly 100 carats of brilliant diamonds in pear, round, and marquise shapes to create a Point d'Alençon lace-like design. Can you imagine wearing that around your neck? Gorgeous!

Thanks to a heavy-spending holiday season and a financial hubbub that may well impact many paychecks, shopping smarter is a key theme for 2013. However, since we all have our own strategies and preferences when it comes to retail, shopping more intellegently may mean different things to different people.

For starters, there's the quality-versus-quantity ideology. While some of us may prefer to save by shopping at fast-fashion stores, others might prefer the method of saving up and splurging on one or two big-ticket over the course of the year. If the latter sounds like your 2013 shopping plan, keep reading! We caught up with the fashion director of Barneys New York, Tomoko Ogura, for expert insight on what investment items folks should consider this year.

While some items on Ogura's list feature familiar brands (Manolo Blahnik, Hermés), others are from equally stylish, if lesser-known, labels such as Hoorsenbuhs, Greg Lauren, and Delveaux, which-for

Getty ImagesEver wondered what other Shine readers are wearing? We've finally asked in our new monthly series: What Are You Wearing Today?

Each month we'll have a different theme and a dedicated space (on the right side of the Shine fashion page) where readers can upload photos of their clothing, accessories, and beauty look. Last month's topic was nails, and we received nearly 100 submissions--we even got a photo from "Jersey Shore" star Snooki! But our favorite manis belonged to a Shine reader named Mari Borrega--her polka dot and rhinestone tips won the title of Shine Reader Look of the Month. Take a look at all the awesome nails Shine readers were rocking last month.

This month's topic is EMERALD GREEN. It's Pantone's official color of 2013 and we're already seeing the shade everywhere, from classy dresses and handbags to playful rain boots and nails. Please send photos (through email or Twitter) of how you're wearing emerald green. We're dying to see the creative ways you're showing of our

.Those of us who shop at Target generally do so for two reasons: First, it's a one-stop shop where we can get home goods, media, beauty products, and, uh, Hunger Games merch. Second, Target has sold consumers on its trendier Targét image, without gouging people at the checkout.

In a savvy move, the mega-chain announced today that it is extending its holiday-season price-matching policy to year-round. Says a Target rep: "If a guest buys a qualifying item at a Target store and then finds the identical item for less in the following week's Target circular or within seven days on Target.com, Amazon.com, Walmart.com, Bestbuy.com or Toysrus.com (including Babiesrus.com) or in a local competitor's printed ad, Target will match the price." This means that the best prices might not come straight from Amazon anymore - and your online price hunting can be taken from the web, straight to the store.

Think of the '80s. Immediately, one conjures up images of neon, finger-less, lace gloves, and Madonna. Now, try the '60s. Our typical associations are tie-dye, peace signs, and Jefferson Airplane songs. But in the era of Instagram and instant gratification, of personal style blogs and immediate access to fashion shows, the signifiers of the aughts are much more murky.

In this time of personalization, the most recent decades are already having trouble defining themselves, argues The New York Times. No one is identified as being "totally aughts," and the uniform of the '00s hasn't quite appeared in hindsight yet. The NYT has pointed out a couple of reasons for this lack of clarity: First, temporal distance - the aughts were, in fact, less than three years ago. Secondly, as former Lucky editor Lauren Sherman explains, "Because fashion is so accessible to everyone now since prices have gone down so much, and people buy more clothes than they used to, trends
