When beginning my tie collection and branching out from basic colors, this was the first creative tie I tried out, and it really set a standard.  The colors blend together richly to create a beautiful sepia swirl, which can either be casual (for a bowtie) or very elegant, depending on what it's worn with.  Something about its aesthetic makes it wearable for just about any clothes combinations, and it blends in to just about any look.  There are obviously a few exceptions, such as pastel colors, but this is the ideal tie that's a jack of all trades.

Also, it's a great size and it holds its form better than any tie brand out there.  These two qualities also make it much easier to tie than other ties, so for someone who knows how to tie bowties but finds the process frustrating, I would encourage this, as it is far more cooperative and naturally slips into place with a full, symmetrical look.
