Is it acceptable to ask what you should wear to an interview?

second interview attire thread of the week, same answer as before, suit up man

No.

If you don't know, wear a suit.

The only time I've not worn a suit to an interview, the guy specifically told me that I didn't need to wear a suit or I knew the guy already and it was an informal interview, like at a restaurant.

Suit up unless you're told not to.

Asking is too passive and will get you overlooked. Demand the information you want.

It's understood that you wear a suit. Anything less is at your peril.

What you wear on a daily basis has zero impact on the expectation in most fields that you wear a suit for an interview. Maybe some engineers or O&G people will say otherwise, but in most every white collar profession where folks wear what you wear every day, they anticipate suits for interviews.

my soon to be wife works in HR.

she told me not to wear a suit to an intra-company interview.

If someone asked me what to wear to the interview, it would set off some bells for me that this person might not be a very mature person or not that bright. Not meaning to call you names, but don't ever ask a potential employer that. If you're unsure, ask a friend. Or as others have said, wear a suit. Better to be overdressed than under dressed.

Always suit. Never hurts to be overdressed. If you have a 2nd or 3rd it may be appropriate to ask, but always suit up for the first.

your mom should have taught you that...If she is dead i am sorry. Go naked...then sue them when they don't hire you for religious discrimination.
