Ah, Fashion Week. Parties! Celebs! Crazy outfits! More parties! We’ve rounded up the best. Click through for some of the week’s most showstopping moments.

This season kicked off with serious celeb wattage: Kim Kardashian debuted a new gray hairstyle at Tom Ford, while Ashley Graham and Whoopi Goldberg showed up to support Rihanna’s return to NYFW at Fenty x Puma. The Hilton sisters showed up everywhere from Oscar de la Renta to The Blonds, while Nicole Kidman and Naomi Watts took in Michael Kors’ closing-day show.

With major brands opting out of showing in New York City this season, there was room for new talent to shine. Among the standouts: Area’s punchy colorful sportswear, Matthew Adams Dolan’s exaggerated silhouettes infused with school-girl cool and Italian-based brand GCDS – who not only officially established underboob as a trend to watch, but closed the show with a surprise strut from Teyana Taylor.

Kaia Gerber, Cindy Crawford’s 16-year-old daughter, took the NYFW runways by storm with a debut appearance at Calvin Klein. Her signature strut (which we imagine took a few practice lessons with mom) also made an appearance at Alexander Wang, Fenty x Puma, Coach and Marc Jacobs.

The booze is always free-flowing somewhere during NYFW. The Post’s favorites were Tom Ford’s nearly naked bartenders, who served up everything from champagne to Shake Shack burgers, while the lucky few who made it into Alexander Wang’s backyard Bushwick affair sipped Budweiser (because Bushwick) while taking in a joint performance by Ja Rule and Ashanti. Philipp Plein’s cabaret-inspired extravaganza featured rapping by Nicki Minaj and some booty-shaking courtesy of Teyana Taylor.

At long last, diversity in all shapes, genders and colors is gaining traction on the runways. Shout-outs to Christian Siriano (who showed that anyone can rock a slipdress), Eckhaus Latta (who proved with a gorgeous age-inclusive casting that age is nothing but a number), and Chromat (where men rocked womenswear like pros).

Designers are increasingly taking risks with venues, and this season took show-goers literally everywhere: Public School won for its too-cool Chinatown alleyway, while Carolina Herrera went full-on uptown at the MoMA. Cinq a Sept offered city views for days atop the Beekman Hotel, while Monse took it back to school in an actual basketball court. Ralph Lauren off-roaded, showing at his garage in Bedford Hills, New York – which is chock-full of vintage cars collected by Lauren.

Yellow! From fringe-y focks at Naeem Khan to neon numbers at Delpozo, the hue was anything but mellow.

Sometimes it’s all about the staples. Victoria Beckham showed classic silky shifts, while Tibi channeled sunny days with breezy white separates. Michael Kors’ roomy silhouettes scream stylish jet-setter, while Mansur Gavriel’s ready-to-wear debut starred anything-but-basic coats.

It’s not fashion week without a little over-the-top craziness, including glittery heels from Libertine, embellished corsets from The Blonds, and Jeremy Scott’s slinky metallics.

Oscar de la Renta designers Laura Kim and Fernando Garcia upped the fashion ante this year. Showing at Sotheby’s uptown, models arrived on the runway via escalator dressed in glamorous cocktail frocks. Some were covered in sequins, others were spun from pink ombre tulle. All were lessons in how to make an entrance.
