Rory's style here is NOT business. You can't dress yourself like that if you're working for an investment bank or in any related finance/accounting/tax job with customer contact. A super thin tie like that just makes yourself look like a Justin Timberland or usher wannabe ...
Bisping in this picture looks like a partner of a big4 firm or investment bank. Not super conservative with those brown shoes and blue suit, but with the fact in his mind: I can afford it ....
I don't like Rory's style. It's not mature, it looks very teen"ish" and like he's trying too hard. If you want to dress stylish, doesn't matter whether it's business or street: keep it simple and basic with just the right amounts of accessories and that certain something and people will compliment you ...
But whatever. This is just a phase .... He's an incredible fighter!
