While we don't consider ourselves frequent vacationers--unless you count drooling over the lavish hotels and tropical resorts on Jetsetter as official travel plans--we do know that organising a getaway can be a stressful task. Between booking the airline tickets, selecting the perfect hotel, and packing all the essential clothing, it's easy to overlook some of the small yet important details, like putting together top-notch travel attire. Fortunately, your WWW editors have done the latter for you! After sifting through thousands of photos, we've rounded up a stellar cast of fashionable celebrities who all know a thing or two about building the best en-route outfits, from Melanie Laurent's expert layering to Natalia Vodianova's chic and polished mix. And of course, we've also included loads of similar key pieces to ensure you're always departing and arriving in style this season. So sit back, relax, and enjoy today's edition of What They Wear: Airports.

WHO: Florence Welch
WHAT: Arriving at LAX earlier this year.
WEAR: Leopard-print coat; printed t-shirt, black skinny jeans; black flats.
WHY: Casual separates, like a t-shirt and jeans, always make for comfortable plane attire, but we recommend following in Welch's footsteps and incorporating a statement-making jacket into the mix for a warm and luxurious finish. To achieve a similar look, start by picking up Wildfox's Love is Everything Tee ($77) and Diesel's Skinny Straight Jeans ($130). Next, try Alice + Olivia's Leopard Print Trench Coat ($347), which will work well if you're headed to colder climates, or check out MinkPink's Leopard Cover Cardi ($88) if you're in the market for something lighter.

WHO: Melanie Laurent
WHAT: Spotted at Nice Cote d'Azur Airport in France late last month.
WEAR: Maje Leather Jacket ($561) and trousers; Zadig & Voltaire scarf; vintage hat; Christian Dior sunglasses; black patent leather peep-toe heels.
WHY: Lightweight layers are key when constructing the perfect en route ensemble for the summer season, as Laurent show us. Scarves and small jackets can easily be added or removed to adjust to changing climate, while topping everything off with a hat is a wise idea if you want to hide unpolished hair. If you're on the hunt for these travel essentials, don't miss Old Navy's Linen Moto Jacket ($30) or ModCloth's A New Leaf on Life Scarf ($18); both have neutral tones, so they will work well with a number of outfits. Finally, grab Bop Basics' Panama Short Brim Fedora ($98) to give your overall look a bit of zing!

WHO: Alexa Chung
WHAT: Photographed arriving at London's Heathrow Airport two months ago.
WEAR: Vintage t-shirt; Moto Pink Jamie Pants ($80); Chanel bag; vintage sunglasses; Russell and Bromley shoes.
WHY: It's generally a good idea to keep your accessories minimal and fuss-free when building your travel outfit, especially if you need to rush from one gate to the next. As Chung demonstrated, a petite across-body bag is the perfect hands-free carrier, especially if you have loads of luggage! If you fancy Chung's on-the-go ensemble, don't hesitate to pick up American Apparel's Vintage Twin Cities Ford Threadbare T-Shirt ($30) and her exact Moto pants. As for the bag, we're quite smitten with Calvin Klein's Madison Leather Crossbody Bag ($138) and Marc by Marc Jacobs' Totally Turnlock Percy Crossbody Bag ($198).

WHO: Eva Mendes
WHAT: Arriving at LAX three months ago.
WEAR: Brown lace cardigan; Louis Vuitton Alize Stole ($820, 866.VUITTON); light-wash jeans; Versace Abbey Shopper Bag ($2275, 888.721.7219) from the S/S 11 collection; Frye Sabrina Boots ($298) in Burnt Red
WHY: When it comes to travel footwear, flat leather boots are an excellent alternative to sandals or heels, plus, they instantly give a laidback outfit a polished finish. And while we certainly love Mendes' exact Frye boots, we're also fans of Steve Madden's Frencchh Leather Boots ($150) and Timberland Earthkeeper's Cabot 2.0 Boots ($200), so be sure to snag a pair before your next big trip!

WHO: Natalia Vodianova
WHAT: Snapped arriving at Nice Cote d'Azur Airport in France early last month.
WEAR: Tan tweed blazer; light blue button-down shirt with white collar; cropped skinny jeans; Louis Vuitton SC Bag ($4350, 866.VUITTON) in Blanc; snakeskin loafers.
WHY: While Vodianova's button-down shirt and cropped skinnies make for an ultra-chic combo, her ladylike tweed jacket and snakeskin flats give the overall ensemble a sophisticated and of-the-moment look. To recreate Vodianova's A+ off-duty mix, be sure to grab a button-down shirt, like Vintage Havana's Collared Button Down Shirt ($60) and a slim pair of cropped denim; Citizens of Humanity's Cropped Thompson Skinny Jeans ($198) will definitely fit the bill! To give your outfit that extra bit of Vodianova panache, add Boden's Rainbow Tweed Jacket ($248) and Stuart Weitzman's Snake-Embossed Loafers ($325), and you'll be ready to hit the town upon arrival!

WHO: Dakota Fanning
WHAT: At LAX late last month.
WEAR: Textile Elizabeth and James Fairfax Tee ($75) and James Distressed Linen Blazer ($395); distressed boyfriend jeans; Proenza Schouler PS1 Large Leather Satchel ($1995); Celine wooden platform heels from the S/S 10 collection.
WHY: Styling a pair of slouchy, cropped jeans with a lightweight blazer and platforms is a sure way to keep your travel attire feeling relaxed, but looking stylish. To execute a similarly savvy ensemble, try Joe's Jeans' Rolled Best Friend Jeans ($163) in Patricia with Topshop's Pale Peach Co-Ordinating Linen Blazer ($120). Just remember to pair both of those finds with either Tory Burch's Tatum Wedges Sandals ($295) or Nina's Sheona Sandals ($89) to further achieve your Fanning-inspired look.

WHO: Zoe Saldana
WHAT: Arriving at Nice Cote d'Azur Airport last month.
WEAR: Lanvin tweed jacket from the Pre-Fall 11 collection; striped top; light-wash skinny jeans; Lanvin bag; Mymu The Ceci 07 Wedges ($298).
WHY: Saldana's neutral mix is understated, yet visually interesting, thanks to the mix of materials and textures courtesy of her tweed jacket, linen wedges, and leather bag. To get similar essentials, grab Madewell's Josie Four Pocket Marled Cardigan ($83), Betsey Johnson's Vall Peep Toe Wedges ($90), and Olivia Hariss' Two-Tone Flap Satchel ($278), and you'll be ready to head to the airport in no time!--Jessica Baker
