MICHELLE OBAMA WEARS ROYAL BLUE CUSTOM CHRISTIAN SIRIANO DRESS TO DNC

On the first day of the Democratic National Convention in Philadelphia, Penn. on Monday, Michelle Obama took to the stage to deliver her last convention speech as First Lady. This year, we've seen the FLOTUS celebrate the Obama Administration's final lap in office with marigold Narciso Rodriguez,glammed-up Givenchy Couture and even Prince-friendly purple for lunch with Queen Elizabeth. But for the occasion of her opening night address, the First Lady let her words take center stage while wearing an understated, cap-sleeved custom Christian Siriano dress.

In the Democratic Party's electoral color of royal blue, the dress was on the subtler side of Mrs. Obama's sartorial spectrum. But as The Hollywood Reporter's Booth Moore tweeted: "Interesting she went with such a low-key look. Almost like she's saying, 'This isn't about me.'" Of course, it wasn't — alongside a star-packed audience that included Demi Lovato and Sarah Silverman, among others, FLOTUS was there to support presidential candidate Hillary Clinton.

Siriano — an American designer — has dressed the First Lady only once previously, with the asymmetrical lace dress she wore to pay respects to the slain police officers in Dallas, Tex. on July 12. 

This was a decidedly less somber event, and a reminder of how much we'll miss Obama and her consistency when it comes to tastefully cool outfit choices.

CROP TOPS AND JUMPSUITS PROVED POPULAR AT THE FIRST PANORAMA MUSIC FESTIVAL

The producers of Coachella inaugurated the first Panorama festival this weekend on Randall's Island in New York City — coinciding with a brutal heat wave hitting the eastern United States. But that didn't stop fans from coming out in droves to see the likes of Kendrick Lamar, Sia, FKA Twigs, Arcade Fire and many more musical acts hit the three stages. Even models such as Kendall Jenner, Gigi Hadid, Molly Bair, Anna Ewers, and Hanne Gaby Odiele made it out onto the fields. 

Fashion-wise, concertgoers mostly kept it simple in midriff baring crop tops or easy jumpsuits and overalls. While some floral or semi-sheer maxi dresses could have felt right at home at Coachella, the vibe was definitely more "New York," meaning an abundance of head-to-toe black looks, as well as a general streetwear bent and ease.

LILY ALDRIDGE IS A CELEBRITY WHO ACTUALLY DRESSED FOR THE HEAT WAVE

Breaking news: It's hot as balls in New York City, so dressing for a day that will likely feel as if you're wrapped in a blanket of heat and humidity isn't exactly motivating. Seeing celebrities traipsing about the Big Apple as if 90-degree weather is merely a social construct doesn't help either. (Exhibit A: Kim Kardashian wearing a knitted dress and thigh-high boots in the Hamptons.) Luckily, Lily Aldridge is aware of how stifling the city can get at the end of July and she appropriately dressed for it, too. Let's break down the model's prime summer look, shall we?

First, her Reformation two-piece set in white is perfectly cropped and made from lightweight linen, a winning combination that's both comfortable and chic. Her Tabitha Simmons sandals are both playful and interesting with those perforated leather details. The suede shoulder bag (from The Row and in a pretty pastel blue) is slouchy and roomy enough for laid-back summer activities. Her sunglasses are Ray-Ban, naturally, because UV protection should always be taken seriously. Lastly, Aldridge sported a sleek low bun, the ultimate sweat-proof up-do.

Celebrities, take note! This is how you actually dress for the weather. And if you want to challenge the hot drink in the model's hand, here's a little science tidbit for ya: A warm refreshment can actually cool you down.

ZOE SALDANA OWNED THE 'STAR TREK' PREMIERE IN GIVENCHY COUTURE

It has been well-documented that Zoe Saldana has a certain penchant for outer space. In 2014, the actress told Badass Digest that she believes there are better parts for women in the solar system than there are here on Earth, and that mentality has led to leading roles in critically acclaimed films like "Avatar," "Guardians of the Galaxy" and J.J. Abrams's "Star Trek." But we on this planet thoroughly enjoy when Saldana returns to Earth — presumably shuttled in by SpaceX's latest contraption — to give us a taste of her otherworldly chicness. 

For the world premiere of "Star Trek Beyond" in San Diego, Calif. on Wednesday, Saldana arrived in a shin-length periwinkle blue mermaid dress from Givenchy's fall 2015 Haute Couture collection. With teensy, bejeweled spaghetti straps and an embellished bodice, the piece actually resembles a leotard that her "Center Stage" character would've worn on-stage with the American Ballet Company. (TBT.) Her stylist Petra Flannery even thought to match her shoes and subtle eye makeup with the gown — a difficult feat based on that pastel coloring.

The whole look is a far cry from the Dolce & Gabbana pajama set Saldana wore all over town on Monday, but that simply goes to show her impressive sartorial range. She should touch down on Earth more often.

FAMOUS PEOPLE STAYED COOL IN HOT PRINTS THIS WEEK

Do celebrities experience weather? This was a legitimate question posed by Fashionista's Dhani Mau in Slack this week, as we wondered how these people manage to wear anything more than a moisture-wicking slip dress without self-combusting into a cloud of crease sweat and body odor. 

Celine Dion is case in point: the singer is going through a renaissance right now under the stylistic direction of Law Roach (who also works with Zendaya) and it's a series of nonstop sartorial hits. She hit the town this week and it was as wondrous as it was bold, proving Dion should never not be clad head to toe in Versace and Gucci. 

Meanwhile, Ellen Pompeo, Tracee Ellis Ross and more celebrated Marc Jacobs's new fragrance decked out in the designer's loud resort 2017 collection, while Cara Delevingne wore sparkly camo pants at Comic Con and Julianne Moore embraced bright stripes. All in all, this week proved that even as the temperature goes up, it pays to turn the volume up on prints and patterns.

MONDAY WAS A DOLCE & GABBANA PAJAMA DAY FOR ZOE SALDANA

Fashion pajamas certainly aren't a new phenomenon, but Zoe Saldana just took it to a whole new level, displaying an impressive commitment to the comfy aesthetic. In New York City on Monday, the actress was spotted wearing two different PJ-based looks. For the first, shown above, Saldana paired a button-down Dolce & Gabbana pajama top with skinny jeans and mustard-yellow pumps. The second look (below) incorporated the same top — but this time, Saldana went full-on slumber party, wearing both the top and matching printed pants, as well as green lace slides.

There's a lesson to be learned here: It's totally acceptable to wear pajamas anywhere and everywhere — especially if they're #FashionPJs from a label like Dolce & Gabbana. Maybe think twice about those rolled Old Navy pants and Hanes tank tops everyone, for some reason, considered acceptable to wear to class in 2004. Zoe, we applaud you for continuing the fight to make PJ's great again.

CHANEL HONORS ITS ATELIER AT THE FALL COUTURE SHOW

Atelier Jacqueline is normally located on the fourth floor of the Chanelheadquarters at rue Cambon. Madame Jacqueline specializes in tailleur (or tailoring), which means that the atelier is devoted to structured clothes rather than the flou atelier that concentrates on softer lines and fabrics for dresses. On Tuesday, in the circular theater where the Chanel couture show was set, the desks, drawings, pins, needles, fabrics and all of the tiniest details — like a summary sheet for certain garments showing their respective stage of completion and signed off by each specialized worker — were on display. In fact, the entire Chanel atelier temporarily moved. The backroom "petits mains" (or "small hands") as they are called in French who bring the sketches to life became the center stage for a collection that is worthy of the majestic label of haute couture.

It is hard to imagine the amount of work and resources required to make an haute couture outfit, but with the backroom as the main attraction, the audience could see the precision, details and materials used. The finished products from Madame Jacqueline made up the opening sequence of the show, with the classic Chanel suit updated in gold and black tweed with a high shoulder treatment and shorter pants; in brown tweed with open neck lapels and satin trims; and in grey tweed with a round high collar and splattered embroideries. These permutations of the classic suit are the bread and butter of the collection. As the show progressed, more marvels came along: a coat made of squares in shades of blue and grey; a glass beaded dress with a front panel over tulle; a light beige floral and feathered long dress with black bows; and a black and white 3D plastic embroidered jacket and long skirt.

Over the past decade, Chanel has invested in purchasing all of the traditional small artisan houses that specialize in embroideries like Lesage, or hat making like Michel, and provided each house with a new business structure in order to prosper. The survival of these skilled workers is essential to the fabric of Parisian fashion — and not only for Chanel, as they work with all of the established fashion houses in the city. As he took his bow, Karl Lagerfeld even walked arm-in-arm down the runway with members of his atelier, making for a moving moment of appreciation.

These Chanel haute couture garments are the result of the work of these ateliers outside of the house combined with Chanel's own — a unique system of making clothes that can only exist in Paris.

ELIE SAAB SHOWED MOMMY AND ME COUTURE GOWNS ON THE RUNWAY

Elie Saab's couture shows are a highlight for anyone who's a fan of high-glamour gowns and awards-season red carpet contenders. The designer's signatures — intricate beading and embroideries, sequins galore, floor-sweeping silhouettes, liberal use of appliqués — have made him a go-to for occasion dressing, and many a celebrity (and a very fancy bride) has had a major milestone moment wearing one of his grandiose pieces. 

But what about the little girls who dream of wearing a princess dress of Elie Saab caliber to their birthday parties, family weddings, holiday gatherings or school photos? No longer are they an ignored segment of the couture market. On Wednesday in Paris, Saab's characteristically glitzy fall 2016 couture collection had one noticeable addition: Child models walked the runway alongside older counterparts wearing miniature versions of their gowns. The youngsters were styled in an age-appropriate manner, with sweet, bedazzled headbands, beaded bracelets, a very natural beauty look and flat shoes. Check out those gold glitter ballet flats!

Sure, there probably aren't too many life events that would require a pre-teen to wear a handmade couture piece that costs upwards of $10K, but should that occasion arise, we'd love to see the looks on the (very privileged) little ladies' faces when their pretty, pretty princess dreams come true.

CALVIN KLEIN ENLISTS KATE MOSS, GRACE CODDINGTON, FRANK OCEAN AND MORE FOR FALL CAMPAIGN

On Tuesday evening, Calvin Klein took to Snapchat to reveal the latest batch of talented actors, models, musicians and, in one case, an editor starring in its fall 2016 global campaign. Following spring's major multimedia effortfeaturing Kendall Jenner, Justin Bieber, FKA twigs, Fetty Wap, Kendrick Lamar and many more, the American brand has just shared videos on Snapchat of Kate Moss, Grace Coddington, Margot Robbie, Frank Ocean, Cameron Dallas, Henry Rollins and footballer James Rodriguez talking about falling in love and flirting.

Update: The full campaign has arrived! In addition to the aforementioned names, Calvin Klein's fall campaign also stars Bella Hadid, Lola Kirke (both of whom were teased in behind-the-scenes footage released back in March), Anna Ewers, Presley Walker Gerber, Roos Abels, Young Thug, Zoe Kravitz, G.E.M., Mo’ne Davis, Sonoya Mizuno, Yung Beef, Antoine-Olivier Pilon, Aomi Muyock,  Cuba Tornado Scott, Selah Marley, Kacy Hill, Keith Ape, Mark MacEachen, Tommy Genesis, Yung Lean and a group of street cast models. Photographer and filmmaker Tyrone Lebon once again captured all the imagery, which will roll out across print and digital mediums throughout the season.

Just like the spring campaign, the foundation of this project is the "I ___ in my Calvins" tagline, as well as over 50 intimate, short interview and performance videos starring the many faces of the season. On Wednesday, the video and photography content is all available together on the "My Calvins" site for 24 hours (see the main film and Frank Ocean's above), where visitors can watch the clips and read a zine about key campaign stars.

It's all meant to feel real and self-directed, to encourage sharing among the brand's younger audience. There's also a musical component: select stars, including Bella Hadid, have curated Spotify playlists and visitors can also generate mixes based on different #mycalvins moods.  (Bella's includes, of course, music from boyfriend The Weeknd.)
