Lise Charmel Grace Infinie Blue Halter Swimsuit

Grace Infinie takes the halterneck and gives it a deep plunge front, cut low into a V and bridged by a narrow strap across the gap — enough to keep the shape secure without closing off the neckline. It's a cobalt blue, worked in a solid knit that holds its colour and shape well against sun and chlorine both.

The straps run up from the plunge to a small ring at each shoulder, a tonal metal fitting rather than fabric-on-fabric, before continuing up as a halter tie that knots at the back of the neck. That tie is where you set the fit — pull it in for more lift and support, looser if you want the neckline sitting lower.

Where it differs from a lot of plunge-front suits is the back: rather than leaving it open, Lise Charmel have kept full coverage down to a high, shaped seat, so the support you get at the front is matched by real coverage behind. It's a suit built for swimming as much as sunbathing, not just a going-in-the-water version of a going-out top.
