Aptly named the Muscle T-shirt – because what’s the point in working out if you can’t show off the results? – adidas by Stella McCartney whips up this sleeveless design. Made from organic cotton (chiming with the British label’s dedication to sustainable fashion), this relaxed style is topped with a scooped neckline and signed off with the logo printed across the chest. Whether you’re planning on perfecting your Upper Cuts or would rather sweat it out at spin, team it with the Truepur leggings.
