Alright ^~^, I was also wondering if I could go on and post the app, and send in a request to join when the group opens again. Also are sweaters allowed?
Of course! And yes, sweaters are allowed - students can get pretty creative with the uniform if they want, so long as they're wearing some portion of it (like any sweater with school issued skirts or pants, or the blazer with their own jeans, etc).
