I spent some time looking at all the Amazon bow tie options and I'm glad
I chose this one. It is 100% silk, dry cleanable, feels like decent
quality and looks great with my new tuxedo. When I ordered it 2 weeks
it cost $15.99 plus $5.99 shipping (total: $21.98). Now it is $17.99
but fulfilled by Amazon and so eligible for free Prime or Super Saver
shipping. I like the new deal better. I like that this bow tie comes
from a "real" brand. With some of the cheaper generic ties sold by
multiple sellers, who knows what you will get. It doesn't come with any
instructions, but adjustments are easy (you loop one end through a
small metal d-ring and back and then stick a small metal bar at the end
into holes labeled by length. As for tying it, I found instructions on
Youtube.
