Christina Aguilera emerged from a bit of a hiatus from 'The Voice' -- she sat out Season 4 -- looking her very best while promoting the upcoming fifth season in a blush micro mini by Alaia. She shed some excess baggage, ditched the ubiquitous crimson lips and wowed us. It inspired us to take a look back at her recent style.
Ankle-length skinny jeans in faded, grey hues were hot earlier this year, and they look to remain the pants du jour of celebs. Lucky for you, they are easy to find and wear. Grey is the new black. It's less severe and goes with anything, from loose, voluminous late summer tops to layers, like cropped leather hoodies and scarves
Those British gals -- so stylish and so bold with their brows. We've noticed a trend among British beauties and English roses where their eyes are framed by bold and thick, yet well-manicured, brows. A thicker, fuller brow is more youthful than one that's overarched, overplucked and too thin. Bushy brows are in, especially for autumn -- as long as they are well-groomed.
Jean shorts (aka Daisy Dukes) are a summer staple. The more tattered, the better, whether you bought them that way or took scissors to an old pair of jeans and started hacking away. Not only can they can make your legs look longer and leaner, they go with everything -- and holes, rips and exposed pockets are welcomed and encouraged.
Jennifer Aniston, the queen of Cali casual, and Kate Upton, among others, recently demonstrated the many ways to work this trend.
Summer is murder on stick-straight hair -- humidity is the enemy of sleekness, and heat leads to a general dryness and lack of shine. So rather than fight the elements, beachy bedhead waves allow celebs to be artfully disheveled and messy on purpose.
The "I just woke up" look can be styled in a variety of ways, like Olivia Wilde's defined semi-curls or Selena Gomez's tumbling tendrils.
Summer 2013 has been the summer of black leather. It's everywhere, made all the more perplexing by how thick and heavy it is. Regardless, even in July -- one of the hottest months of the calendar year -- black leather skirts are all over the place. Better still, there's one appropriate for you, no matter your personal style.
To keep cool, the hem can rise a la Miley Cyrus, or you can get girly with flirty pleats like reality star Audrina Patridge.
Demi Lovato is known for her love of tough girl black, but for summer she's apparently toned it down by going with grey and white instead. At the same time, the singer and 'X Factor' judge kept her makeup -- smoky eyes and glossy nails -- in her signature shade, along with her sky-high heels.
Like the look? Then you'll love this: We recreated it for around $160.
Flower-print dresses are perfect for summer, especially when the hems of the frocks are short. They're fresh, fun and flirty, just like the buds of the season. And since flower-print apparel is easy to find and comes in a variety of cuts and colors, there are options for all of us -- short, tall, petite, curvy, girlish or glam.
Here, you'll see model Karlie Kloss went with a geometric neckline, while celebutante Paris Hilton was kinda darling in black and white.
Katie Holmes became a style icon by virtue of the media coverage bestowed upon her when she hooked up with, procreated with and married Tom Cruise. All eyes were on the cute 'Dawson's Creek' actress, so she had to step it up and go from girl to woman in a heartbeat.
She and Cruise are now divorced, but that hasn't stopped her style from evolving.
We're in the thick of summer with the sun at its hottest, but even so, our favorite fashionable celebs are still turning up for events looking flawless and like they never break a sweat. This week's winners were Selena Gomez, who was ravishing in red at the ESPYs, as well as Malin Akerman, who was bold in blue -- but sadly, the lovely Vera Farmiga overdid it with a billowy black gown.
Here are the best and worst looks of the week.
