Hey Harvey, don't Cardinal Newman has a uniform? I remember when I was in Brighton, both GSCEs and A level had sets of uniforms to follow. Obviously, if the 6th form requires suits and school tie, it will be stupid to not wear one. If they don't, it is best to commission some odd jackets and trousers for school, if you are keen on the sharp looking side. TBH, forget what you should wear, the girls in Newman is generally the hottest in the region, beats my old school and Brighton Hove High.
