Last week Rebecca Gallagher, 25, from Gowerton, said she found this label in a dress she bought.
And yesterday a second message was revealed to have been found sewn into an item from their Swansea store.
BuzzFeed has asked the retailer for more details but it has refused to comment further.
Yesterday a third SOS note was found.
Karen Wisinska, 28, said she found this plea for help inside khaki three-quarter length trousers she bought for £10 at a store in County Fermanagh, Northern Ireland.
It reads: "We are inmates of the Hubei Xiangna Prison, working on clothing lines for export over a long period of time. We work 15 hours per day and the food we eat wouldn’t even be given to dogs or pigs. We work as hard as oxen in the field. We call on the international community to condemn the Chinese government for the violation of our human rights."
BuzzFeed has reached out to all three women for further comment.
