This was worn under a uniform. The fabric is sturdy, but not bulky, so it's easy to pair with a blazer. The size is LL, but my son, who usually wears men's M-L, wore it. He didn't seem to like a very tight fit. He liked it and wore it many times, so there is some wear and tear, such as pilling, but I think it's a good deal for those who don't mind.
