Everyone has their opinions about using furs. I choose not to use real animal furs. But I love using faux fur! It works as a great substitute and you do not have to harm a small animal! Plus it can be washed in your washing machine, compared to real furs that need to be dry cleaned. Most faux furs are 100% acrylic, a man-made fabric. The pink coat is Oscar de la Renta.
