If you're planning on hitting up the summer festival circuit then a bag like Miu Miu's is ideal - it's not only practical but guaranteed to get extra likes on Instagram. This piece has been crafted in Italy from silver leather that’s covered in scores of light-catching sequins at the front and quilted at the back. The detachable chain strap and adjustable belt means it can be slung over one shoulder or fastened around the waist.
