Calvin klein is one of the best and high end quality end product when it comes to both men and women. All the products of CK are outstanding and durable as well.
But one should be really careful before purchasing the product. As you can see there are lots of Clothes, watches, assesories, cosmetic are available which looks exactly like origional but their quality will be cheap. So I would reccomend buy only from authorise dealers, shops, sites to avoid duplicacy.
