It depends on the company. Google, as an example, sends you an email when you interview that there's no need to dress up for the interview - wear what you're comfortable in, the interview is about your skills. I'd say about half the places I interviewed at basically said that they weren't expecting me to dress up and I wore a nicer everyday outfit. If the company doesn't give you guidance, I think it's easiest to ask. Usually you're dealing with a recruiter at the company and they want to get someone good hired, but ultimately the choice to hire won't be theirs. They're not going to want you to get a "no" decision simply because someone interviewing you didn't like your dress. They know the people who will be interviewing you and what they're expecting. If the company keeps track of numbers for these inside recruiters, those recruiters are going to want to look like they're bringing in good people - that they have good judgement when bringing people in for interviews. They won't want their numbers to be bad based on your dress - based on a technicality. How crummy would that be - your numbers are worse than another recruiter's because you wouldn't advise candidates on how to dress and they were denied because of that? You can always fall back to being more dressy, but I think asking is the easiest.
