Atlein has gone through something of an overhaul — production shifted to Portugal, prices lowered, and collections pared back to two a year — and this fall lineup, Antonin Tron’s first collection in a year, marks the reset moment.

Style-wise, it was all about homing in on the label’s origins. Tron has made a name for himself working jersey into sensual designs through careful draping techniques — and here he offered flattering tops and dresses that molded to the body, playing with asymmetry and playful gatherings. Lace trimming on silky dresses added femininity to the sporty lineup, while vegan leather pants and workwear shirts toughened things up a bit.

Reflecting the label’s ecological bent, Tron used a Seaqual fiber made from plastics fished from the sea, for his jersey fabrics.

“The idea of the brand Atlein is that it’s dedicated to the ocean, the Atlantic Ocean, nautical sports, the sensualness of water sports,” he said, noting that surfwear inspiration is a recurring theme of the brand.

One look resembled a deconstructed wetsuit, the bralette shaped out of a material resembling Neoprene, paired with trim tracksuit bottoms and a blazer. Sprinkled throughout were pieces of elevated sportswear, part of his Offshore line, stamped with a new brand logo.

“There’s always this dimension of an athletic woman, the body in movement, in tension,” he explained.

A polished video presentation showed models walking the concrete halls of a converted industrial site, the Fondation Fiminco, interrupted at times to show dramatic drone shots of waves breaking on a beach.
