For a classic black swimsuit that won't break the bank, we're turning to good ol' swim experts Speedo who are breaking away from that budgie smuggler image. The Women's Eco Endurance+ Medalist Swimsuit Navy (£26.50) is an update of one of the brands classic models, redesigned with the eco endurance+ fabric made from 50 percent recycled yarn. It's also 100 percent chlorine-resistant, meaning you have years of laps to go before thinking about swapping it in for a newer model.
