DS is going into P2. He is tall but very narrow. HIs blazer from last year is 24" and looking rather neat on the arms and getting short although a good fit on his chest; we can get away with it for a little while but not lng. I have ordered the next size up which is 26" from the school logo shop but it is ridiculously wide, the shoulders and chest are huge and he looks like a scarecrow. There is no way we can transition between the two, he will need something before the larger one fits.
I thought I might take him into JL to try some on but looking on line they only have one navy blazer without a logo.
Any suggestions? Needs to be navy. School uses beau Brummell viscount blazer but we don't need to use a particular supplier.
