I am 33 years old. I interviewed a while ago for a mid-senior level position at a contract research company. To set the stage, I will say that most people in my line of work dress rather casually (denim or khakis, sport shirts), including those at this company (for instance the hiring manager was wearing jeans; only the ceo and one vp were wearing suits). Granted this was a Friday visit, so I don't know how they dress Mon-Thurs. For my initial interview, I wore a navy suit (sb, two button, side vent, average lapel width), white point collar shirt, coordinating navy tie, black captoes. I have been invited back for a second interview at the end of this week. The suit described above is the only suit I own that I would consider wearing for an interview and I can't buy a new charcoal suit before the end of this week. I'm planning on wearing the suit again, but with a light blue pinpoint oxford button down, wool charcoal tie, and perhaps wine longwings. The last bit is the sticking point. I know some say never to wear longwings with a suit, so there's that angle, and others say not to wear black shoes with a blue suit (looks like a uniform). Lastly, many would say never to deviate from black captoes for an interview, but this is not a finance job. Counterpoints: I like the shoes, wine goes with navy, it's a second interview at a casual company. Thoughts? Thanks. PS- If deemed necessary, due to longwing and button-down oxford content, I will pose this thread over at the ask andy forums.
