An investigation has found that some major high street stores have been selling real fur labelled as acrylic. One mystery shopper brought a coat from TK Maxx which has a no fur policy. It was later found that the coat had a real fur collar trim. The RSPCA has urged shoppers to double check any items that have a fur trim. As a guide if skin or leather can be seen between the hairs at the base when they are pulled apart, the fur is real. If a weave, or material, can be seen at the base, then it is fake.
