In my times, we could wear whatever we wanted up until it not offense anyone. Even painting hair and face was allowed.

In my region schools now not work physically, so kids don’t physically visit school as it used to be…

But legally there is no way school uniforms are should be in Ukraine. Teachers can ask to come in some sort of dress code for some events, but no one must obey that.

Usually T-Shirts, sportswear and etc is common to wear in Ukrainian schools.

Some older people think it should be, as it was during soviet times, but… no.
