This is always been an interesting part of the tech community to me so I'm glad you asked this.
Personally I've found companies that value their developers enough are more relaxed about look, but that extra relaxation varies.
My mentor at one company I interned at had some minor ear piercings, full arms along their tattoos, and he was in a leadership position among the programmers.
My first job let the few devs and designers get away with jeans, flip flips, and graphic tees. Everyone else was generally expected to dress business casual.
My current job, which has a lot of startup culture, is somewhat more relaxed. Most devs here just wear jeans and any kind of shirt they want. Tattoos are fine, and while no one here as piercings I know it hasn't been a factor against people who applied. The fact that a higher-up here commented that we could be getting high at work and it'd be fine as long as we got our work done shows the higher relaxation.
I'd agree with most people here that like most jobs, you should be clean and presentable so as not to distract coworkers. You don't need to smell like aftershave, but you shouldn't reek to the point where others can't focus.
I have really enjoyed the relaxed dress codes that follow our professions. I've had many times where I'm at a relaxed social gathering, I tell people "these are the same clothes I go to work in," and they're completely jealous. Really, not wearing button downs is one of my favorite coding perks :)
