This purple Marc Jacobs The Logo cotton sweatshirt is part of the label’s Colour Collection, designed to celebrate comfort, self-expression and creativity. Cut for a relaxed fit, this crew neck design showcases the brand’s monogram and features long sleeves, ribbed trims, a back loop at the collar and supply label at the straight hem. Marc Jacobs calls this shade ‘Purple Potion’ – well, it must be a love potion, because we’ve fallen for this jumper.
