Shaftesbury School staff and students are preparing for fun and fundraising on Thursday.
Year 13 student Rosie tells us how staff will be involved in Rag Day.
The event is different this year due to COVID safety restrictions, but Semley resident Rosie was determined that it would go ahead.
The students are raising money for CLIC Sargent and an antiracism charity. You can donate to their appeal here.
