Glad I jumped on the summer-weight VBC deal from Luxire a few months ago. The school is a giant oven.
I've noticed a few staff members dressing better this year; a few more ties than usual, but that could be the honeymoon-first-week-of-school.
As I slowly replace my ties with more tasteful patterns, textures, and materials I'm also buying them wider. At this point, 8cm is much wider than the Black Fleece and mall brand ties, which I think are around 6.5 cm. 9 sounds bib-like.
