Yea. I've been slowly growing out of just jeans/tshirts for a while. About 5 years ago I decided to get in better shape and stop dressing like a slob. Of course that doesn't mean dropping the relaxed jeans and t-shirts altogether. I also didn't want to be a boring suit or wear awful business casual crap. I see enough of the cookie cutter kahki-and-baby-blue-shirt bros around. Worse yet is the ones that can't even get button down shirts that fit them properly. It's like they're a baby-blue hot air baloon.
Here's what I've been doing recently:
* Properly fitted non-faded jeans unless the fading works with the shirt. It doesn't have to be skinny hipster jeans, but it should fit better.
* Nerdy shirts, but never if it's a haynes square cut T. They have to be similar cut to the American Apparel standard fit T. Get rid of the baggy shit.
* Some button down shirts, but never baby blue, pink or some shit unless it's fitted or has some style. The best ones I have are custom taylored. There's a few places online that will make you taylored shirts for dirt cheap. I got mine from http://taylorstitch.com/
* I've got a personal taste for wool suit vests. They work well with un-tucked shirts and arn't as boring as a normal suit.
If you gotta wear a suit, don't goto a department store unless you want to look like a sales droid. There are a ton of small to medium size designers out there that have much more cool stuff.
Boring white button down shirt? Hell no, try this:
