I'm into the skinny ties with fitted jeans or skinny jeans and high top tennis shoes. Regular ties to along with bright colors for spring.
Also when done right you can wear producer pants and tennis and still pull it off as office wear. Which is what I do...
I'll post some pics of the tennis/shoes I currently wear...

No longer wearing sweaters over shirts with a tie.
Instead the sweater alone makes for a more spring wear.

Short sleeve button down shirts are a must and you gotta add the skinny tie.. I'll post more pics of that.
