On a ligher note, a man should always wear double cuffed shirts to work, for the use of cufflinks (I find the most in-offensive to be the elastic double ball style, but a plain brushed aluminium style, or something sporty/related to work like a $ on one side, the euro on the other etc works well. You want to project success not bargain basement shirt finds.
I only buy double thick material shirts from people like T.M.Lewin (

or Thomas Pink (

Have a look through the mens sections on the sites.
Suits have to be crisp, clean and well dry cleaned - and shoes extremely polished.
GOOD HINT - I also agree that the only jewellery you should wear is a great watch. We've all heard that women first look at your face, your watch then shoes or whatever
- thats why I wear a Rolex GMT Master II (
http://www.rolex.com/collections/oyster/fich_gmt.html)
I have the red and blue version listed in the collection....
But guess what - ITS A FAKE - full (japanese, ok not swiss made) oyster wrist movement wind up action, keeps the time like a dream, looks EXACTLY the same... and the key is that the retail price is only £2500 (I think around $4000) so its not one of the 30 or 40 grand versions which no-one would ever believe I could afford. Anyone asks it was a 21st birthday gift from my father.
There are good fakes and bad fakes. track them down... for example
www.4swisswatch.com
I am in no way plugging these sites, just saying they look pretty good - I actually got mine from a street vendor in Spain, this is just spam i got recently, so they probably can't be trusted.
You can wear a mediocre suit with a good shirt, good watch, tie, cufflink and shoe/belt combination and pull it off.
As far as casual is concerned, I'm a jeans and t-shirt man, but the "rolex" makes that look good too.
