I am looking for summer shorts for my 17 YO DS. I know there's lots about and he's try quite a few from Next and Asos, but he wants them to reach his knee, not be floppy/baggy, and be very comfortable. I know this last comment seems obvious, but for DS this rules our jean shorts for example, and although I know he can get jersey shorts, we're looking for something slightly smarter. Just slightly mind. Any ideas?
