• Square neckline sits wide and flat across the collarbone, giving the top a clean, deliberate edge that a round neck simply wouldn't deliver.
• Cropped length hits just above the waist, with subtle ruching gathered along the hem that adds soft texture without bulk.
• Long sleeves fit close to the arm from shoulder to wrist, keeping the silhouette streamlined all the way through.
• Polyamide fabric with elastane moves with the body and holds its shape through a full day - no bagging, no pulling out of place.
• Minimal and unbranded, making it an easy layer that sits underneath or stands alone without competing with anything else in the outfit.

This top earns its place in an athleisure rotation precisely because it doesn't look like an afterthought. The square neck and close-cut sleeves give it a considered feel that takes it well beyond the gym bag - pair it with a high-waisted wide-leg jogger, as the model does here, and the cropped length creates a natural break that makes the whole look feel intentional. For running errands or a low-key weekend, throw a zip-up hoodie over the top and let the neckline peek out. It also works tucked into high-waisted tailored trousers when the occasion calls for something slightly more pulled-together but still relaxed in spirit. The stretch fabric sits close enough to move freely through any activity, yet the ruched hem detail keeps it from reading as purely functional. A simple chain necklace and trainers round things off neatly.
