The latest “RHONY” cast trip took place on a private island, but Carole Radziwill’s go-to hair accessory won’t run you millions.

The reality TV OG revealed on Instagram Stories this week that she wore Kitsch Zig Zag Headbands during the tropical getaway. And at just under $11 for a pack of two, they’re a total steal.

“The best headbands,” Radziwill wrote, while resharing a Bravo post about the episode.

It seems plenty of shoppers agree with her; Amazon’s sold over 40,000 packs in the last month alone, making them the No. 1 best-selling headbands on the site.

The nostalgic, non-slip style is coming back in a big way lately. Hailey Bieber has also been wearing zig-zag headbands on repeat — including the $525 Miu Miu version she modeled for the brand’s fall campaign.

But when it comes to ’90s style, Radziwill is practically the blueprint. A born and raised New Yorker, the reality TV icon regularly shares her favorite capsule wardrobe-worthy finds.

Earlier last week, she appeared on SirisumXM’s Page Six Radio show wearing the Faherty NY Giants Raglan Long-Sleeve — a cute style she shouted out as “the best tee” on Instagram.

And with “RHONY” just getting started, it’s safe to say there’s a lot more style inspiration in store.
