L.A.M.B. School Boy Blazer

Oh la la! How preppy is this L.A.M.B School Boy Blazer? I know that the temperatures are rising, so taking off layers is a bit more appropriate than adding them, but this jacket is crisp and I think it would look great with skinny jeans or a full skirt. Or maybe I am just obsessed with Gossip Girl returning next week so I am secretly coveting prep school attire of my own.
