I have three Zegna ties that I got at the Barney's sale, and I can't tell if they are Zegna's mainline or Z line. On the underside of the tie, it says "Ermenegildo Zegna," overlayed on a huge Z. I know that the big Z in the background is the Z line's trademark, but on my Z suits, it just says "Zegna" over the Z, not the full name. So I can't tell, and I don't suppose I really care, but I'm just curious. I don't think it would matter, as the ties feel the same, and retail for similar prices (about $140), only difference to me seems to be that mine are slightly more modern patterns, with slightly more vibrant colors. Does anyone know more?
