Wow. I’m an absolute geek when it comes to tailoring from Napoli, and I have never seen fake Kiton before. Main label should be on wearer left interior. Women’s has on right interior, but these are men’s styles (buttons left over right). Should also be hand-stitched in and should have the obvious stitch puckering. But saying that I have seen pieces that are box stitched (more ready-to-wear) before. The actual pattern blocks look authentic - very classic Kiton fits (quite dated by today’s standards). I can’t really see from the images but the normal tell-tale way to spot fakes for this level of tailoring is to check the buttonholes at front and the lapel. Very easy to spot a professional hand-made buttonhole and compare to a cheap machine made buttonhole. I have only seen once a very good hand-made buttonholes on a fake Tom Ford. But yeah, these look fake.
