MikeF says it's a turn-off and LAGuy just made a point in another thread that showing up in a Kiton suit and Patek watch was almost akin to showing up in a polo shirt and jeans. Now maybe it's just me, but Patek watch aside, I really don't think that the interviewer is going to be able to tell an Oxxford (since their cuts are probablyy similar) suit from even a Brooks Brothers suit... If he doesn't know the difference, how can he be that turned off by it? When you walk in to someone's office properly dressed, I would think that they'd subconsciously take not of this and not look much further than that unless there's something specific that stands out and grabs their attention. You'll shake hands, then sit down and start the interview. I really don't think the interviewer will be doing an up-close inspection of your button holes to see if they're hand-sewn or not. Unless he feels your arm, in which case you probably won't want the job anyway;p, I highly doubt he'll be able to tell if the fabric of the suit you're wearing is a super 100 or super 180. Aside from the fact that your suit fits properly, I really don't see what easily identifiable characteristics would indicate to a person that doesn't know a whole lot about these types of things, that you payed 2k+ for it as opposed to even 1-1.5k for a Canali or something.. And lets not forget that the people that do the recruiting for investment banks are either associates who have shown promise and good judgement, or VPs. In either case they're easily making 150k+/yr and probably wearing a half-decent suit. It's not like you're walking in to their office wearing a top-notch suit and they're wearing something from men's warehosue or whatever it's called... So again, assuming they CAN recognize the difference, they might care. But in all likelihood, they won't be able to tell the difference. My brother has a black suit and if he's standing 5-10 feet away, unless you specifically look for things that distinguish my suit from his (mine cost 4x what his did) or touch the fabric, I really don't see how you'd know the difference unless you have a VERY keen eye for that sort of thing. Even with things like side vents, surgeon's cuffs and ticket pockets, it might tell him that it's possibly custom and not your run of the mill suit, but aside from that it's guesswork... Canali and Kiton differ by several thousand dollars in price, how is the average guy that doesn't pay too much attention to these things gonna know the difference? My answer is: he won't. Anyone else have thoughts on this?
