Eres Cassiopee strapless swimsuit

The Eres Cassiopee strapless swimsuit is the house at its most pared-back, prioritising fit and finish over flourish.

84% Polyamide, 16% Elastane, in black, UK 10 — the kind of detail that's easy to miss until you're holding it.

Built to outlast a season or two, which is really the point of buying at this level.
