We are changing our PE top. You can carry on wearing the old one (light blue with burgundy owl) for as long as you like but when you buy a new one, you will need to know your House (Eastgate, Westgate, Southgate or Northgate) because each one will now have a different coloured PE top. The shop/on-line will know which colour is associated with which house but just in case:
Eastgate: Blue
Westgate: Yellow
Southgate: Red
Northgate: Green
