We get asked about old school uniforms and the answer is simple.
First check with your school to see if they would hand out spare uniform to someone who may be in need. Some schools have a stall for Pre-love school uniforms summer fayre ect.
Second option would be to use a business such as www.oldschooluniform.co.uk who will help you through the process to your school uniform.
