Fashion chain Primark is investigating after a second shopper in a Swansea store found a label in clothing, complaining of "sweatshop conditions" and "exhausting hours."
First, Rebecca Gallagher spotted a label reading: "Forced to work exhausting hours" next to the washing instruction of her top.
Now, Rebecca Williams from Porthcawl, has revealed how she found another label reading: "Degrading sweatshop conditions".
The two women both bought their dresses from the same Primark store in Swansea.
Rebecca Gallagher said: "I was amazed when I checked for the washing instructions and spotted this label."
"To be honest I've never really thought much about how the clothes are made - but this really made me think about how we get our cheap fashion."
"I dread to think that my summer top may be made by some exhausted person toiling away for hours in some sweatshop abroad. It made me feel so guilty that I can never wear that dress again."
Rebecca Williams said: "I was really shocked when I saw the label saying it was degrading sweatshop conditions."
"I used to to shop a lot at Primark but not so much now. The label has made me think about how my clothes are made.""I have no idea who made the label or how it got there - but it does make you think."
Primark has faced criticism over its ethics, after a factory collapsed last year in Bangladesh, with more than 1,000 workers killed.
Hundreds worked for a Primark supplier, and the high street chain has pledged to pay compensation to injured workers and the families of those killed.
It insisted it has "a code of conduct in place, to ensure products are made in good working conditions and all employees are treated fairly."
Asked about labels being found in these garments from a Swansea store, a spokesperson for Primark said: "We are investigating the origins of an additional label which has been found in one of our dresses and whether there are issues which need to be looked into."
