IMHO - although every one of the suits and advice previously mentioned were dead on accurate and are incredibly nice, as a 1L interviewing, you do not want to appear too snotty or wealthy. Keep in mind that the majority of attorney's are not good dressers and are more accustomed to Brooks Brothers and Jos. A. Banks, rather than Cannali and Britoni (yes, there are huge exceptions, myself included in them). However, when we interview 1L's, we certainly expect navy suits, white shirts, red conservative ties, that are nice, but not overly expensive (again, you don't want your client thinking that you are over billing him just to get a nicer wardrobe). That being said, by all means, get your nice suits (once you are practicing, you can make your own rules). But for initial interviews, conservative pieces (both in price, label, and appearance) are highly recommended.
