Here is the tag, and the message from the official Borrelli Instagram account. As you can see when your guard is down bc you are shopping at Harry Rosen (the last place you would expect a fake) it is very easy to get fooled by the tag.
In fact on their final cut website this exact shirt with this exact tag is still for sale and described as Luigi Borelli in their description
So it appears they have pulled down 3 of the 4 fake Borrelli shirts they were selling from the website...but they continue to sell the blue one. Do they think it is somehow better to sell only one fake instead of four???
