My daughter's school in SA had summer and winter uniforms, and enforced it. There was a civvies day each term and the girls were invited to make a donation which went to charity, but it was voluntary and they didn't keep records of who contributed, or how much they gave. No-one minded at all, but there shouldn't be any pressure to go along with it.
TBH, I find the whole idea of people in workplaces wearing fancy dress - and being expected to pay for the "privilege" - ridiculous.
