‘And Just Like That’ fans baffled by Sarah Jessica Parker’s ‘unhinged’ hat: ‘Is that a pillowcase?’

This hat’s a head-scratcher.

Sarah Jessica Parker shared a peek from the set of Season 3 of “And Just Like That” on Instagram Monday, and while her retro shoes seemed to be a hit, many fans questioned her choice of headwear.

The “Sex and the City” star, 59, wore a floppy gingham “cloud hat” by designer Maryam Keyhani, whose artsy designs retail for hundreds of dollars.

She paired the headpiece with Dr. Scholl’s wooden slides ($120) and a vintage 1970s Ossie Clark dress with a multicolored tiered skirt, carrying a canvas tote for the scene.

She wore the wild look while filming with “AJLT” co-star Sarita Choudhury in Washington Square Park over the weekend, although she swapped her tote for a Pierre Cardin crossbody at one point.

Fans had plenty to say about the “Hocus Pocus” star’s ensemble, like one who wrote, “Outlandish and I’m LIVING for it! ❤️.”

“Only an icon ( like you) could pull off that hat. 👏” another fan commented.

Others were more critical of her headwear, like one who wrote, “Wearing a diaper bag as a hat, clever!” and another who wondered, “Is that a pillow case [sic]?”

“Wearing a pillow on your head is a godsend! You can go to bed on any bench in Manhattan,” a third quipped.

Along with pillows and diaper bags, the star’s “unhinged” topper drew comparisons to Strawberry Shortcake, Holly Hobbie and Little Miss Muffet — but her retro footwear scored high points all around.

“Manolo Schollos❤️😂😂” one fan joked, with another adding, “And just like that, Dr Scholl’s have a sales spike 😍.”

This isn’t the first time this month Parker has shown off a statement headpiece; one the Met Gala 2024 red carpet, she teamed her custom crystal-covered Richard Quinn dress with a fantastic Philip Treacy fascinator.

As for Season 3 of “And Just Like That,” we have a feeling this isn’t the last wild hat Carrie Bradshaw will wear.
