Square-Neck Bodysuit

A long-sleeve bodysuit with a clean square neckline that sits straight across the collarbone, cut in smooth stretch jersey with no visible seams to sit invisibly under high-waist skirts and trousers. The square neckline is structured enough to hold its straight line rather than curving or stretching into a rounder shape through the day, which is what keeps it looking neat under blazers and structured tops. The fitted sleeves run the full length to the wrist for a base layer that works through colder months, and the snap closure at the base keeps everything anchored so the fit stays clean whether you're sitting, standing, or reaching.

Smooth, opaque stretch jersey with good recovery, so it holds its shape through the day rather than sagging at the crotch closure. Hand wash cold or use a gentle machine cycle inside a wash bag; the snap closure at the base is delicate, so avoid twisting it in the wash or letting it catch on other garments, which can bend the snap out of shape. Lay flat to dry, and check the snaps are fully done up before washing so they don't work loose in the machine.

As a base layer designed to sit under other pieces, it replaces the need to tuck and re-tuck a separate top, keeping a cleaner line without buying a longer shirt just to avoid gapping. The seamless cut also means less fabric is trimmed away in construction compared with a top built from multiple stitched panels.
