And a couple of more things...
...no french cuffs (unless you're a CEO)
...no ties lighter than your shirt
...no deeply colored shirts...maroon, black...
...no leg showing...get some long socks...
...cuffs on the pants, especially light weight fabrics
...pants should break over the shoe...

A few good tips on keeping your suits looking new (From a website someplace with a few extra thoughts tossed in)
• Store suits on the original hanger when not being worn. Wide hangers keep the shoulders from sagging. Wool has memory - wrinkles will hang out.
• Never button the suit jacket or zip the pants while storing. This is the only time you can keep your pants unzipped.
• Brush your suit after each wearing. It takes off the surface dirt.
• Dry clean your suit no more than 3 or 4 times a year. Remove them from the cheap ass plastic bag that the drycleaner put them in so they can breath.
• Find a reputable dry cleaner (you get what you pay for).
• Always clean both jacket and pants together. Colors may undergo subtle changes in the dry cleaning process.
• Request hand pressing of the jacket (lapels need to be rolled).
