I agree with Chrissi, you will stand out and be remembered for being just a little bit different.In the current economic climate, I think different but not completely OTT is good.
So here's hoping you and your tie are center front in the interviewers minds.
I hope they reply speedily too and don't keep you hanging around.
I am very fond of ties I wore one to school for 14 years, so I had to be !!
My children all had to wear ties, hats, caps, and blazers when they were at school in England, so I taught them how to do ties, seemed like the circle was complete then. the student became the teacher.
My favourite photo of them, is all 3 stood in a group, 1st day for Emma and back again for the boys. I was so proud of them I thought my heart would burst.
