If you can't get a sense of someone's culture fit from talking to them how is looking at what they wear going to help in an interview? [Sure you can see if they come in wearing jnco's or look to see if the indie music/game/movie shirt is "cool" enough.] The only thing I think is reasonable to assume from clothing is how interested they initially are in working for the company.
Maybe someone with a lot of startup experience can enlighten me.
Then if they say you can take off the jacket, tell them you're holding in the pit stains. I always like to get the interviewers laughing.
Something like this (without the tie) is what I would wear: http://media-cache-ak0.pinimg.com/736x/14/7f/10/147f1019bf4b...

In short -- just dress in something that makes you look professional and attractive.
For most startup interviews I'd think you should go with the startup uniform: slacks, button up shirt with no tie, and dress shoes.
Edit: my apologies for only answering for men. No idea what a woman should wear to a job interview.
Good new for me. I love wearing a suit.

I'm being a little glib, but I think it's always best to stick with your guns, especially in a job-seeker's market :)
FWIW, when I interviewed at Intel and wore a suit, the security guard commented when I walked in that I was overdressed.
I 100% stuck out as a sore thumb, but that was okay. I considered the three cases:
1. I should dress up and they will ding me if I don't
2. they don't care
3. I should not dress up and they will ding me if I do
I'd be right in 2 out of 3 cases. And in the third: well, flushing people for doing what is expected of them by a large fraction of the community is crazy, so it's good to find out.
(No, I didn't get the position.)
A lot of companies dress smart casual but most also won't think of someone negatively if they "over-dress" for an interview (since, frankly, we all know that's the game that is played).
I interviewed at one place where the owner was in flip flops. So I felt dress up in slacks and a polo shirt.
I interviewed at a very big financial institution so I wore a suit and I had one of my interviewers tell me, twice, that they DO NOT wear suit and ties to work.
Long-sleeve button-down and slacks probably works in most cases, but again for startups/tech companies you probably want them to be more cool than corporate. No pleated khakis or high-starch polyester shirts.
It shouldn't really matter that much since the whole reason developers don't dress up to work is because it's not the dress that matters, it's the work. In reality it matters anyway, at least at many companies. Try to find photos of their team at work on their website, dress a bit nicer than that.
I didn't want to over or under dress so I wore dockers, dress belt, dress shirt tucked in and a tie. I think the best idea is to hit business casual - not full suit but not casual.
The founder was wearing shorts and a t-shirt. He didn't say I was over dressed and I got the job. I would have been really uncomfortable in a suit.
Day 1: Tan Dockers, nice shoes, a low-key long sleeve button up Tommy Bahama shirt I got on clearance, a belt. The Dockers were on sale too. I already owned the shoes and belt.
Day 2: Black Dockers, same shoes as day 1, a long sleeve blue patterned shirt that was also on clearance, same belt as day 1.
I had to bring stuff to the interview. I carried in my orange Marmot backpack.
