Coastal grandmother style gets sporty with new summer collaborations

The coastal-grandmother wardrobe did not need a total reset this month. It needed better reasons to borrow from sport, and June delivered them in the form of a Marine Serre and Under Armour capsule, a major H.Lorenzo store opening in West Hollywood, and a pair of swim and soccer collaborations that made relaxed luxury feel less precious and more useful.

Marine Serre x Under Armour was the sharpest of the lot. The debut capsule tied Marine Serre’s directional point of view to Under Armour’s 2000s sportswear archive and baselayer language, while also marking 30 years of athletic performance for Under Armour. It launched June 5, with a Paris pop-up running June 5 through 7, then expanded globally later in the summer on UA.com. For readers who like the coast to look polished rather than costume-y, the appeal is obvious: a technical layer under linen trousers or a crisp sweater carries more edge than a full logo outfit ever will.

Retail also sent a clear signal. H.Lorenzo opened a 9,000-square-foot flagship in West Hollywood at 8801 Beverly Boulevard, consolidating its separate men’s and women’s stores into one larger luxury space. Designed by Oliviero Arch Baldini, the new address reads like a statement that prestige shopping still matters when the edit is strong enough. That is the real shift for this audience: the store itself becomes part of the fantasy, a more considered backdrop for buying clothes that should feel collected, not cluttered.

The most trend-driven move came from American Eagle and Umbro, whose limited-edition capsule leaned into blokecore and World Cup energy with jerseys, shorts, sweatshirts, skirts, jackets, hats and more. American Eagle’s product pages put most pieces in the roughly $34.95 to $79.95 range, which makes the collaboration easy to test without behaving like a forever purchase. Still, this is the item most likely to read as noise unless the soccer reference is already part of the wardrobe. The useful pieces are the ones that can be softened, not the ones that announce the trend too loudly.

Kylie Jenner’s KHY stayed closer to the coastal brief with Dear Summer, Love Khy, a summer-getaway collection built around 100% silk, swim, jersey and cotton. The brand, founded in 2023, positioned the lineup around summer travel, warm nights and evenings out, which is exactly where this aesthetic has room to grow: off the sand, on the terrace, and dressed up just enough to leave at sunset.

The cleanest beach-to-town crossover may have come from Clare V. and Left On Friday. Their limited-edition swim capsule paired Clare V.’s colors and prints with Left On Friday’s functional suits, including the LOF x Clare V. Bandana at $75 and the Hi Hi Bottom at $125. That is the sweet spot this month: pieces that can handle swimming, surfing, lounging and wading without losing their polish. The coast looks best now when the clothes are built to move.
