I interviewed on Wednesday for a position as an Office Manager at a Senior Citizen apartment building. They called yesterday to set up a second interview for tomorrow.

I wore a black pantsuit to the first interview. The person interviewing me was wearing a blue turtle neck sweater and a pair of cotton Khakis. I did feel a little overdressed, however, not so much that I felt uncomfortable. I'm trying to decide if I should wear a button up shirt with a cardigan or a gray jacket with black pants tomorrow.

Do you think it's appropriate to dress down for the second interview even though the office seemed pretty casual? My gut is telling me that it's not. The company is doing 4-5 rounds (I know that's a lot, too much to explain here) of interviewing and I do not have 5 suits for each interview. I think it's a little extreme to buy a bunch of new suits when I don't even have the job. So, when (if ever) is it appropriate to dress a little more casual for these interviews?

No do not dress down. You want this job so you always dress for the position above the one you are applying for. They grey jacket and black pants. You can wear that black suit with a different blouse.
