Generally speaking, no one cares what you wear to a programming interview. If it wouldn't cause people not to sit next to you on the subway, you're fine. Sure, there are outliers -- Goldman Sachs probably won't hire you unless you show up for the interview in a tuxedo, and some brogrammer-laden startups won't hire you unless you dress exactly like they do -- but they're rare, and recruiters will warn you ahead of time if you're walking into that kind of situation. Personally, I would rather hire a solid programmer who needed some guidance on how to dress than a solid dresser who needed guidance on how to program, but that's just me.
