I had several themed sweaters, tops, and button front shirts when I taught elementary school. I even had a blazer with embroidered giraffes on it from QF. Lots of teachers wore holiday themed clothing.
When I started teaching middle school and Junior high I stopped wearing holiday themed clothing. I felt a bit self-conscious being the only staff member wearing those kinds of items. I was younger and more concerned about what people would think. I ended up donating them all.
I wish I had kept a few of my favorites. As I've aged, I've become less concerned about what others think I should or shouldn't wear.
