Dip your (well-heeled) feet into the buzziest trend of the season: Barbiecore — awash in pink, pink and even more pink. Between early-aughts nostalgia (particularly for anything real-life-Barbie Paris Hilton wore during that era), leaked footage of Margot Robbie living life in plastic for the upcoming “Barbie” movie, and Valentino’s splashy new Pantone shade of fuchsia (dubbed “Valentino Pink PP,” and seen on our cover), there’s no sign of this femme aesthetic slowing down soon. We’re partial to Mach & Mach’s glittering, bow-topped stilettos. Slip them on for your best Elle Woods bend and snap.

Loved-up Jennifer Lopez paraded Lele Sadoughi’s heart-shaped cluster earrings post-honeymoon in Capri. You can score those swoon-worthy statement studs and other gem-toned items from the designer’s Age of Brocade fall collection at her first New York store. Located at 387 Bleecker St., the West Village shop carries everything from embellished headbands, jewelry, sunglasses, socks, hair clips, hats, makeup pouches and handbags to Sadoughi’s adorable new Barbie collab.

You don’t need a key for Tiffany Lock, the legendary brand’s inclusive new jewelry collection. The four gender-neutral bangles — available in 18-karat yellow, rose and white gold, with or without pavé diamonds — are a modern take on the house’s iconic padlock motif. Meant to signify the bond with others, the bracelets open and shut with an ingenious swiveling mechanism. Secure yours now.

No joke, comedian and Queens College alumnus Jerry Seinfeld is modeling in Kith’s latest campaign. The label’s ongoing collab with Russell Athletic is schooling us with a City University of New York, Queens College and Brooklyn College capsule. In the ads, the funnyman poses studiously in varsity jackets and sweats bearing the crests and logos of his alma mater, as well as fall fashions and accessories. Meanwhile, Kith’s nonprofit, The Kinnect Foundation, has awarded grants to the schools’ scholarship funds. A study in chic.

Isabel Marant is thinking big. The hip Parisian designer has opened her largest flagship yet, at 677 Madison Ave. (replacing her previous store on East 67th Street). The new two-floor boutique showcases women’s, men’s, accessories and the Étoile diffusion line, all in a minimalist setting with trademark ’70s touches. Find Marant’s thick-sole wedge sneakers (a Beyoncé fave) and urban cowboy boots there, along with slinky midi-dresses and oversized outerwear.

Consider it a five-star collab. Last year’s Frame x Ritz Paris hotel capsule was such a hit — Hailey Bieber was papped making out with hubby Justin in the blue cap — that a second one just dropped. The 44-piece limited-edition line includes varsity-style outerwear, slippers, robes, pajamas, tees, unisex cashmere sweaters, high-top sneakers, kids’ clothes and even dog togs, all emblazoned with the legendary hotel’s crest and script. The ultimate in ritzy amenities.
