Yes its a lot of money for a used suit but new trofeo silk suits from Zegna cost about 2300 euros.$275 seems like a lot for a used suit. It looks like it may be a bit dated as well. Is the jacket unvented? I can’t tell from the pics.
It seems that its double vented.
Buttons kinda bother me because they seem like regular plastic. Does Zegna use plastic buttons? Especially on o high end model of theirs? Or the buttons are made of another material?
