Millie Bobby Brown Asked In What Way Her Skimpy Bikini Is 'Flirty'

Millie Bobby Brown stunned fans with her swimsuit body back in December 2023, when she jetted out for a tropical getaway. Sending out low-key bombshell vibes in a floral bikini, the actress posed from a white-sand beach, quickly making headlines for her Instagram photos. The snaps, which are still live on Millie's feed, may have earned over 4 million likes, but they also launched questions. Millie has since made headlines for marrying husband Jake Bongiovi and launching her Florence by Mills Fashion line. In 2025, she's fallen under fire for her blonde bombshell era. This bikini was dubbed "flirty" by a media outlet, quickly prompting some fans to question how a bathing suit can be "flirty."

Scroll for the photos. Opening with a close-up selfie while teasing hints of her curves, Millie stunned against a greenery backdrop, gazing right at the camera with a neutral expression. Showing off her natural beauty while in a plunging bikini top with pops of yellow, blue, and hot pink, the Stranger Things star flashed her toned shoulders, wearing her hair down and styled into a bob.

Wearing cute clips in her hair while going 100% makeup-free, Millie showed her natural glow without any glam, with her second slide focusing on the semi-cloudy skies she'd been enjoying. Making fans swipe for her full figure showoff, Millie returned in her final slide, this time showing off her gorgeous curves and toned tummy while in her strappy two-piece.

Flaunting her trim hips and toned legs, Millie posed with one hip slightly swung, adding a belly chain that further accentuated her enviable waistline. "Santa tell me," a caption read as the Hollywood star gave a nod to Christmas.

The photos were quickly covered by The Daily Mail, which referred to Millie Bobby Brown's swimsuit as "flirty." Fans seemed keen to pick every word apart.

Over 140 fans agreed when one user asked: "What's a flirty bikini? Are other items of clothing flirty? Could my anorak be flirty? Hope I'm not sending out the wrong signals." Appearing to agree, another said: "Lol great comment bravo!" Elsewhere, fans picked Millie's appearance apart, with one fan wondering if she'd had a little work done on her lips. "She is pretty but she's had her lips done and that's not a good road to go down," they wrote.

The above photo came as a promo for Florence by Mills Fashion, launched early last year. Snapping a selfie from her marbled bathroom, Millie Bobby Brown freed the nipple in a baby blue, cropped top and matching shorts undies, repping her trendy label as a caption read:
