Which is context dependent. If I rocked up to any UK client I've known in the alternative outfit you've highlighted, I'd expect some decidedly odd looks. Replace the t-shirt with a shirt and possibly tweak the shoes a bit and we might be getting somewhere, but still.... Which is why, to be honest, I still favour suits - their universality. Other dress codes require a far greater cultural insight to properly judge, both regionally and of the client culture, yet in almost any practical context we're likely to find ourselves within IT, a suit works as a starting point. If your suit isn't comfortable and don't fit then you've found a bad suit; find a better one, which can still be from an ordinary high street retailer and be cheaper than you'd expect.
