To her friends and neighbours in rural Zambia, Margret Chola is just a charming grandmother with a penchant for oversized sunglasses.

But online, she is a fashion legend with 200,000 Instagram fans - after her granddaughter lent her some clothes for a cheeky series of photoshoots.

Ms Chola, aged in her mid-80s, shot to internet stardom after agreeing to swap outfits with her granddaughter and pose for a few snaps, clad in bold turquoise dresses and silver pantsuits.

The photographs were an instant sensation on Instagram, gaining a thousand likes within minutes of being posted on the social media website.
