Martha has become a fashion idol - with fans keen to copy her style. The middle-aged stalker - played by Jessica Gunning - has spawned a series of wardrobe copycats as viewers clamour to get her looks. Outfits for the plus-sized character in Richard Gadd’s smash were put together by costume designer Mekel Bailey.

He scoured London charity shops and put together a wardrobe of mismatched colours and prints to reflect Martha’s inner chaos. And now, websites are putting together lists of where followers can find her mismatched looks for themselves. One, ShopYourTV, has details of Martha’s purple heart print cardigan, worn when she sits at a bus stop outside Donny’s house for up to 16 hours a day, as well as a sparkly cardigan she wears in episode one, which is from Marks and Spencer’s Per Una brand.

The site tracks down more of Martha’s threads including a top from Nasty Gal and a floral blouse from Ann Harvey. Mekel, 35, said he knew instantly who he would channel for Martha’s wardrobe - singer Susan Boyle, Heather from , Pam Ferris and his former headteacher. He said of Martha’s fashion choices: “ I just knew everything had to be used/worn in.

Every thread & strand needed to have years of age. “Little tears/rips/snags/stained all of these imperfections add such depth. So with that 95% of Martha’s and all cast costumes I sourced and found in the glorious charity shops all over London.

“Day by day, week by week, I would go postcode to postcode and some day.
