I agree, but Yoox isn't a small family business, they works with big BIG numbers.
They (sadly) don't care of fake or mislabeled items as they don't care of putting girls jackets on men section as seen some page back.
This.The point is that they couldn't check all the items they bought from stores.Disonest store could send to yoox also used items or mislabeled or relabeled items in the stock they send to them and problems like this could happens but fortunately returns are easy.
I've found the Kent boar bristle too hard for clothes, I bought a brush some times ago but never use it.
I think that a classic horsehair shoebrush, it's perfect also for clothes and more delicate, I use a large Saphir brush.
I use also a supersoft neckbrush only for sweater.
