We have been hard pushed to find elegant and high-performing swimwear, sportswear and underwear, let alone pieces that are all three of the above at once. But London label Prism has reached new heights in hybrid design. Its range of seamless separates allows you to hop, skip, swim and work out without the need to change.

Chlorine- and heat-resistant, quick-dry, stretchy and supportive, these pared-back pieces are timeless and technical. Made in Italy, they are also eco-dyed and constructed using 3D-knitting to eliminate fabric waste.

Going from morning stroll to Pilates class to poolside has never looked (or felt) so good. §
