This Barbie loves a see-through ‘fit.

Dua Lipa rocked another mermaidcore look after her appearance in the blockbuster “Barbie” movie, wearing a red-hot Blumarine dress with a peekaboo thong in new pictures she posted on Instagram Sunday.

The 27-year-old pop star — who performs “Dance the Night” on the “Barbie” soundtrack and also stars as a blue-haired mermaid in the film — wore a crocheted red gown ($2,250) with seashell-like cups as she posed for a series of sunset snaps in Albania.

The “New Rules” singer looked ever the Disney princess as she posed on a rock next to the sea, sharing eight different images from her waterfront photo shoot in a post she captioned, “charging my crystals ✨”

Dua wore her hair long and loose in the photos, turning to reveal a cheeky look at her black thong showing through the sheer dress.

She added a long gold chain with what appears to be a pink crystal charm, wearing various sizes of hoops in her ears and sporting a French manicure.

The “Levitating” singer’s fans were loving the seaside vibes — and her racy red dress — leaving plenty of red heart emojis on the post.

“This barbie is a mermaid ????????‍♀️????” one fan commented, while another wrote, “Nothing short of pure ALBANIAN BEAUTY ✨????????”

“ok miss mermaid,” a third fan added.

This isn’t the first peekaboo thong the “Break my Heart” singer has worn in recent days; she sported a shimmering see-through dress to the “Barbie” premiere earlier this month, revealing both her undies and her nipples in the daring fishnet dress.

Looks like Dua’s not done being all caught up by the sea.
