This may sound stupid, however I honestly don't know. I am starting as a Long term sub in the fall and I have to be there for the school's inservice days before school starts. I will meet the teacher I will be subbing for and attend district meetings and training sessions. I wasn't sure if I should dress up or wear something casual/semi-dressy, or do teachers go in jeans? Any advice would help, I don't want to look like an outcast. Thanks.
