Express Shirt and Tie Guide

Express seems to know their customers well.  They have put together this handy little interactive guide for choosing shirts and ties.  The guide explains all the important elements of shirts and ties.  It also offers some suggested shirt and tie combinations and even shows animations on how to tie different styles of ties.  What I really like about this guide is that it is shows a certain amount of respect to the reader by maintaining a level of sophistication, even for basic information.  Its information is aimed at people who know nothing, without making them feel like they know nothing.
