Hullworth House is one based on tradition and proper etiquette. In other words, you need to come from wealth and wear expensive cloths. Hullworth is the clubhouse specifically for boys, and just like Tennyson House, members get the special privilege of wearing a modified version of the classic blue, grey and white uniform that is in argyle rather than in solid colors. However, there's a reason that this is a privilege; not everyone can join Hullworth, because another one of the main requirements is excellent grades and a decently clean personal record. Fortunately, those who aren't even applicable don't want to be classified with the preppies.
