Okay, so I'm a guy and I'm definitely wearing a suit to my interviews! But my question is the following: Is wearing a nice suit with a vest too much? I love how my navy suit and vest look on me with a specific tie, but I'm wondering if that's _too_ formal. I don't think so but my family is stressing me out by telling me it's too formal. I figure it can't be bad to slightly over dress (as long as I'm not wearing a tux). Any thoughts? Best of luck to everyone with the interview process!
