Rebecca Gallagher, 25, has vowed never to wear the dress she purchased in Swansea over fears it was the result of exploitative working conditions. 

"You hear all sorts of stories about people working in sweatshops abroad — it made me feel so guilty that I can never wear that dress again," she told the South Wales Evening Post.

Gallagher said she rang Primark to complain but was "put on hold for 15 minutes before being cut off".

She added: "I dread to think that my summer top may be made by some exhausted person toiling away for hours in some sweatshop abroad.
