Q: Are these appropriate looking enough for a teacher to wear?

I purchased them in black and would think them very appropriate for a teacher to wear. They are also comfortable.

Q: I’m a 9.5 W, so I’m it sure what size to order?

Not too sure how to answer your query, but if I were you, I'd order both the 9 and the 10 size. Then return the one that doesn't fit... I LOVE these sandals! BUT... I usually wear an 8.5; I ordered up a size to size 9; the sole fit in length, but the straps were way too big and loose, so I had to return them. (Boo Hoo :) Hope you have better luck
