Fashion Week 2015: Every A-List-Packed (and Oh-So-Stylish) Front Row, Party and Presentation

The close pals hug it out at the designer's star-studded cinema-themed show at the Ziegfeld Theatre.

You probably did a double-take when you first looked at this photo of the Broadway icon and her look-a-like daughter, both going for the glam at the Marc Jacobs show.

Bette and Sophie weren't the only mother-daughter duo at Marc Jacobs' Fashion Week spectacular! Debi brought her 9-year-old daughter as her date.

Of course Marc's squad is really strong. Mackenzie Davis, Kate Mara, Dianna Agron and Imogen Poots dressed to impress (and yes, this photo is giving us a major case of hair envy).

We guess the wet hair look is in again for spring! The models show off their backstage beauty at the Marc Jacobs show.

New York Fashion Week is always the perfect setting for our favorite reunions (those would be reunions with Laguna Beach and The Hills stars). Audrina supports her expectant friend at the Kristin Cavallari By Chinese Laundry presentation.

This might be Kendall's last NYFW walk, but don't worry, we still have London, Paris and Milan for your Kendall Katwalk fix.

When you're Marc Jacobs, you can get all the top models to walk in your show.

This isn't exactly a look Irina would wear for a date night with boyfriend Bradley Cooper, but it would totally work if she were to attend a family reunion with the actor. (Make sure to look closely at her skirt – those are theater watchers wearing 3D glasses!)

"I got an email, and then I answered it, and then I flew here for a fitting," the indie rocker said of being asked by Jacobs to walk in his show, where she wore one of most dramatic gowns to hit the catwalk.

The Fashion Police stars take the stage in style to host the Macy's Presents Fashion's Front Row event.

We're not used to Heidi being the only model not in lingerie. The star presents her Heidi by Heidi Klum Intimates Collection on the runway at the Macy's Presents Fashion Show.

There's a lot of Oscar-nominated star power at Ralph Lauren, as Julianne Moore, Jessica Chastain (in Piaget jewels), Alec Baldwin and his wife Hilaria prove that there's little else more fun than being beautiful at a fancy fashion show.

The face of Calvin Klein Underwear wears, well, considerably more clothing at the line's Calvin Klein Collection show.

One of NYFW's busiest front-row attendees finishes the week on a high note, wearing a boho print dress with braids to the J. Mendel show.

The actress embraces the minimalist vibe of Calvin Klein Collection in a slinky white dress and strappy heels.

If you ever wondered what a business shorts suit would look like, look no further than Julianne's J. Mendel outfit.

We're loving J.Hud's outfit at the DKNY show, but we're loving that adorable phone case (featuring five-year-old son David Jr.) even more.

At a party for "Icons," you best believe the divas brought their top fashion game. From left: Mariah Carey, Katy Perry (wearing Saint Laurent and Bulgari jewels, and who posed as Elizabeth Taylor for the issue) and Rita Ora (in Prada) serve up serious glam attitude.

But the supermodels were no slouches in the style department, either: Kendall Jenner (in Calvin Klein Collection), Gigi Hadid (in Balmain for HampM) and Alessandra Ambrosio go graphic in sexy black-and-white numbers.

Sure, the star's Marchesa dress (at the line's fashion show) is lovely, but let's be honest: We're all really here for that ring.

October's Vogue cover girl has a little fun with fashion at the Boss womenswear show, accenting her white A-line dress with hair ribbons, Dana Rebecca Designs jewels and metallic Paul Andrew heels.

How you know Gigi is a pro model: She makes even wearing socks with mules (on the Anna Sui runway) seem like a good idea.

Fresh off her whirlwind red carpet tour at TIFF, the actress hits up NYFW for the DKNY show (that's some very stylish alphabet soup!).

Not only does the supermodel look fabulous at the launch of Burberry Beauty at Sephora – she takes a mean selfie too!

The New York amp Company star designer models the goods (with some help from a few mannequins at a lunch for her fall line.

"I’ve always been a huge Delpozo fan – the second I was introduced to it, I became so obsessed with it because it’s very unique and interesting and it’s very youthful," the teen star tells PeopleStyle of her go-to line for pretty dresses (and no surprise, she's modeling another one at the brand's show!).

If you think a floor-sweeping soft pantsuit sounds better fit for one of the Golden Girls, then you haven't seen Nina's take on it (worn with Adornmode earrings at the Founding Member launch dinner).

Our guest Instagrammer gave the DKNY show a rave review: "Maxwell and Dao killed it!"

There's been a lot of great hair at NYFW, but we're ready to go ahead and call this one for Christina, who sports her long titian tresses loose and wavy at the Marchesa show.

Add them to the list of hottest couples at Fashion Week! The duo makes time for date night at the Marchesa show.

After a appearance at Marchesa with her daughter Sophia, Bette takes a front-row seat next to another celebrity kid for the spectacle that is The Blonds.

Seeing Gregg in his white Fruit of the Loom tee next to Bella in her glittery lace cocktail dress gets us thinking: Isn't it about time they made Marchesa for men?

Also attending The Blonds: The due-any-minute star, who dresses her bump in a glittery eggplant sweater dress and stacked boots.

His fiancée Jamie Chung is a fashion week fixture – which is why we're surprised to see the actor flying solo at the Kenneth Cole new store opening party.

The frequently fringed and boho-fabulous stylist keeps things more simple and streamlined at the Proenza Schouler show.

Also at the Harper's Bazaar Icons party, the celeb-kids-slash-models (she's in Gabriela Cadena) put on their best Blue Steels for the cameras.

If Kylie hadn't been so busy getting ready to model in her brother-in-law Kanye West's show, this would be the ideal Kris Jenner Khristmas Kard. (Kendall's in a Jonathan Simkhai skirt and Michael Kors Collection bag.)

Everyone at Michael Kors's show does what they do best – and that would be looking beautiful for Olivia Wilde and Naomi Watts (both wearing the designer), and shooting photos for Mario Testino.

Christina Hendricks, Kat Graham and Ashley Greene took in some seriously beautiful gowns at the designer's dramatic presentation.

Someone better tell Lorde that she and the Canadian rapper are already "Royals" just by virtue of getting a coveted invite to the Yeezy show.

The model hits the Michael Kors Collection runway with wispy bangs, a crossbody bag and a huge smile.

No longer can our writers challenge Anna Wintour to a game of: The Vogue editor, at the Yeezy show, has upgraded to a rose-gold iPhone 6. Fancy! (Also, celeb watchers should note Jaden Smith not making out with his girlfriend in the second row.)

The model gets a different view of the proceedings – from the sidelines! – in her head-to-toe Michael Kors Collection outfit at the designer's show.

Courtney appears to be offering sitting services. North appears to be skeptical.

Among the leotard-clad models at his show? Kylie Jenner and Bella Hadid.

Talk about desk to dinner! The two stars wear some sexy attire to the Thomas Wylde show.

It sounds like the beginning of a joke – three funny blondes walk into a fashion show – but in fact, it's the well-coordinated front row at Narciso Rodriguez, including Amy Schumer (a fan of the designer's shoes), Jessica Seinfeld (a pal of the designer) and Kate Upton (a supermodel),

The sweet couple got snuggly at the Narciso Rodriguez show, where she wore Melinda Maria earrings and handed out bags of Honest Company beauty products to pals.

They were all smiles for the paparazzi at the Coach show, but once the official flashbulbs were gone, the two teen stars got goofy.

She's not wearing something short, sheer, abs-baring or skintight ... should we check her Kredentials? The star sports an olive jumpsuit at the Alice + Olivia by Stacey Bendet show.

You know that old saying: The couple that wears studded leather jackets together, stays together (at the Diesel Black Gold show).

That stylish phone case (spotted in the star's hand at the Coach show) belongs to PEOPLE Style amp Beauty Assistant Sarah Kinonen, who used it to grab this shot for Insta and to snap an awesome story on PeopleStyle (follow us there!).

Malin Akerman, Samira Wiley and Solange Knowles are so perfectly coordinated at Milly, we have to imagine they all texted each other outfit pics before arriving.

She may have been a judge at this year's Miss America pageant, but she still looks every bit the beauty queen in the front row at Carmen Marc Valvo.

After Victoria showed us what goes into a celeb's NYFW appearance, we'll never again assume that putting these outfits together was a cinch. (These two are at the Alice + Olivia show.)

Two super-cool chicks with rocker roots – we bet these two had a ton to talk about at the Coach show.

Not many designers also model their wares on the catwalk – which makes Ashley's lingerie-clad strut down the Addition Elle runway that much more exciting.

Baby Rafael may only be three months old, but you're never too young to get into fashion, as mom Hilaria, sister Carmen and dad Alec (at the Carmen Marc Valvo show) can attest.

Does every outfit just "go" with a Miss Universe sash, or do you think Paulina has to shop for the perfect look (like her pencil skirt ensemble at Angel Sanchez)?

Apparently, if you get seated next to Kylie Jenner (as Bella Thorne and Serayah are) you get an in-person demo of her new app.
