Julia Fox parties in barely-there seashell bikini after walking DSquared2 runway show

Look at this stuff, isn’t it neat?

Julia Fox went full sexy Ariel after her cameo on the DSquared2 catwalk in Milan Friday night.

While the “Uncut Gems” muse hit the runway in a sheer lingerie-style minidress teamed with matching thigh-high stockings, she later changed into a skimpier style from the new collection for the afterparty: a barely-there bikini top adorned with two strategically placed scallop shells.

Fox, 33, paired the pearl-draped top with an equally microscopic white miniskirt and peekaboo thong.

Showing off both her catwalk strut and her racy spin on “mermaidcore” on Instagram Monday, she thanked DSquared2 designers Dean & Dan Caten in her caption.

“I’ve loved @dsquared2 since way before I could even afford it! (I used to get it using the five finger discount iykyk),” Kanye West’s ex wrote.

“to be in Milan, the city I was born in, surrounded by people who inspire me and push the ‘boundaries’ of fashion is beyond a dream come true.”

Fox is famous for her statement-making street style ensembles and envelope-pushing red carpet looks.

Earlier last week, the actress attended a LuisaViaRoma x British Vogue party in a red sequined Samuel Lewis gown with a booty-baring cutout, which Go Fug Yourself bloggers Heather Cocks and Jessica Morgan hilariously compared to Sebastian the crab.

Perhaps Fox is just really, really excited about the live-action “Little Mermaid” remake?
