after school Watch
No, when I was at school I normally used to get changed as soon as I got home unless I was feeling really lazy. Sometimes if I knew I was going somewhere after school I'd take another sweater or hoodie in my bag, take my school jumper and tie off at the end of the day and change into that. I'd just wear the same skirt instead of going home and changing everything. Sometimes also a change of footwear and socks so it was less obvious I was still wearing part of my uniform.
