Hi there, I have a son at Ravenstone and the only parts of the uniform you have to buy from the supplier are the logo sweatshirt and PE top. Polo shirts and trousers/shorts can be bought from anywhere as long as they’re the right colours, and you can have any kind of swimsuit, school bag, and coat (ie any colour, pattern etc). Not sure what you mean about ‘both kind of hats’ - there are no hats! Apart from a swimming hat.
I hope everything goes well with their arrival. All being well, there should be another Ukrainian mother and son joining Ravenstone before too long, so that may help them to settle in
