#17 Know How to Tie a Bow Tie

and when wearing any kind of tie, you must button the top button of your shirt.  There are few things tackier than an unbuttoned top button with a tie on -- you don't look cool and casual, you simply look sloppy.

And use real bow ties, not the pre-tied ones.

And another thing, cumberbunds pleats should face upward (your dad says it is to catch crumbs.  Not true but if it helps you to remember which way is up...).

At the end of the evening, there are few things sexier than a man with his bow tie untied and the top button of his collar undone.  But leave the cumberbund in tact.

Trust me on this one.
