And you're assuming I'm in past my 20's because.... 
I recently turned 28, Camel Jockey is in his early 20's. Sorry I'm not 35+ and have to resort to boring black suits and plain ties to each occasion like you 
Sorry, dude, but I'm a tie fanatic. Nordstroms, Jos A. Bank, Hugo Boss, and Kenneth Cole tend to have the better quality ties. But, stripes and patterns are the way to go. One can use the tie and shirt to spice up the suit. Whether it be a spread collared or rounded collar shirt. The shirt CJ has is fine. One could go lavender or even white. The tie can have bright colors, but use other colors to tone it down. One doesn't have to have basic black for a suit, but can go dark drown or grey, or even pinstriped. It is recommended to go black.
At 28 you should know by now how to dress for ceremonial events. Generation X and Y (us) tend to be slackers when it comes to this stuff, either we weren't taught, or we don't care. Either way it's sad.
I just telling him, this is what is recommended, and, not to put himself out there. But as the saying goes, "It's better to be over dressed, than to be under dressed
