BUYING a T-shirt has become a bit like buying Christmas cards - you feel a heel if part of the price does not go to charity. The Centrepoint Silver Collection is a limited edition with designs by Duffer of St George, Ally Capellino, Katharine Hamnett and Antoni & Alison. They are priced at pounds 19, pounds 10 of which goes to Centrepoint, the charity for young homeless people.
