Lo and behold the mighty wardrobe staple. Not talking about the plain white T-shirt, but instead these pink cotton-blend jeans from Stella McCartney. Cut to a slim fit with a high waist, the straight-leg pair is sure to make a dent in your year-round collection. If that's not an investment piece, then we don't know what is. Featuring a high waist, a straight leg and classic five pockets. POSITIVELY CONSCIOUS: We’ve joined forces with ethical agency Good On You to give you the power to choose positively. This piece is from a brand that scores well on their key criteria.
