Pom Klementieff channels coastal grandmother style in Zimmermann in Antibes

Pom Klementieff's Antibes lesson

Pom Klementieff did not treat Antibes like a costume change. In the South of France, at Zimmermann’s High Summer 2026 launch at Villa Dorane overlooking the Mediterranean, she wore a pink printed Zimmermann dress with spaghetti straps over a strapless swimsuit, then finished the look with chunky platform sandals, a leather clutch, and reflective sunglasses. The result was less seaside cliché than sharp, sunlit ease, the kind of polished holiday dressing that feels instinctive rather than overworked.

She also made the most useful point first: she did not work with a stylist. Klementieff says she chooses clothes by gut, looking for pieces that make her feel good and move well. That is the real reason the look lands. The dress skims instead of clings, the swimsuit reads as part of the outfit rather than an afterthought, and the accessories add just enough edge to keep the whole thing from slipping into sweetness.

Why this reads as coastal grandmother, not just celebrity resortwear

Coastal grandmother, the aesthetic coined by TikTok creator Lex Nicoleta in 2022, is built on breezy silhouettes, soft colors, breathable fabrics, and the kind of Nancy Meyers-style coastal living that looks calm even when the day is full. Klementieff’s version fits the code, but she gives it a faster pulse. Her pink print, easy drape, and beach-adjacent layers line up with the trend’s love of comfort and quiet luxury, yet her styling feels more mobile and less nostalgic than the classic white-linen fantasy.

That difference matters. Klementieff’s personal style is more experimental and action-oriented than the standard coastal-grandmother wardrobe, which is often read as relaxed knitwear, crisp shirting, and clean neutrals. Here, the lesson is not to recreate a seaside tableau. It is to borrow the attitude: clothes should feel airy, flattering, and ready for movement, whether you are headed to a hotel lunch, a pool, or a late dinner in sandals.

The pieces worth borrowing

The easiest thing to copy is the silhouette. A floaty dress over swimwear works because it solves the practical problems of summer dressing without looking utilitarian. It gives coverage, air, and a little drama, which is exactly why a Zimmermann dress makes sense in this conversation. Zimmermann has a clear ’70s vibe, and Klementieff says she loves its balance of femininity, delicacy, and functionality, a trio that describes the strongest version of coastal grandmother style right now.

If you want the look to translate outside of Antibes, keep the formula simple:

• Choose a dress that moves, not one that sticks to the body.

• Use a swimsuit as a base layer so the outfit feels ready for heat, water, and travel.

• Reach for soft colors or gentle prints instead of heavy contrast.

• Add one structured accessory, like a leather clutch, so the outfit feels finished.

• Finish with sandals that have lift or shape, but avoid anything so delicate it turns impractical by lunchtime.

What to skip is just as important. Skip stiffness, skip obvious effort, and skip anything that makes summer dressing feel like a costume. Klementieff’s own line about age does the work here: as she has gotten older, she has learned what works for her body, what colors suit her, and that discomfort never looks good on her. That is the smartest style rule in the story, and it applies far beyond resort dressing.

The eccentricity that makes it feel real

Klementieff’s holiday packing list is where the celebrity fantasy gets a little stranger, and more interesting. Sunglasses, a swimsuit, sunscreen, and a phone charger are the expected essentials. Then comes the helmet. She also packs a skydiving helmet, and sometimes a skydiving suit or horseback-riding gear, because she lives like a nomad and loves adventures.

That detail keeps the story from becoming too tidy. Klementieff, who is widely recognized for Mantis in the Marvel Cinematic Universe and has roots in French indie films, has long seemed drawn to fashion that can keep up with an active life. She has spoken before about skydiving in poetic terms, and that makes the helmet feel less random than revealing. It tells you she is not dressing for a mood board. She is dressing for movement, altitude, heat, and whatever comes next.

For the coastal-grandmother reader, the lesson is not to copy the helmet. It is to copy the function. Pack for your actual summer, not an imaginary one. A good swimsuit, strong sunglasses, sunscreen, and a charger are not glamorous, but they are the backbone of every elegant holiday suitcase.

Why Zimmermann keeps winning this lane

Zimmermann’s June 3 Summer Escape event in Antibes, where guests gathered at Villa Dorane in looks from High Summer 26, underlined why the label keeps surfacing in conversations about modern vacation dressing. The brand understands that resort clothes have to do two things at once: photograph beautifully and survive real life. Its pieces carry enough romance for a Mediterranean lunch, but enough structure and ease to move from poolside to evening without a wardrobe reset.

That is why Pom Klementieff’s look feels like more than celebrity style. It shows how coastal grandmother has evolved into something sharper and more flexible, a coastal-minimalist code with room for personality, movement, and a little adventure. The trend no longer belongs only to linen, neutrals, and stillness. In 2026, it can also look like a pink Zimmermann dress, reflective sunglasses, and a woman who knows exactly what feels good on her body.
