The swim short is the most versatile piece in any beach or pool wardrobe. Vogue UK notes the women’s swim short as the most practical and stylish alternative to bikini bottoms for active water sports, while Who What Wear UK highlights the high-waist black swim short as the most flattering and versatile swimwear bottom.

Pool: Pair with a coloured or printed bikini top and pool slides. Beach: Style with a rash guard or crop top for surfing and paddleboarding. Beach to bar: Layer a breezy cover-up shirt or mini dress over the top for a quick transition to a casual lunch.
