My son has a lovely slim blanket hoodie from next that he has just outgrown- he’s age 14 but over 6 ft…. Next don’t seem to have any age 15/16 suitable boys one and Google just finds me men’s ones that are massive and Sherpa lined… he just wants a nonlined one with fleece inside. Any suggestions? I have a sewing machine but am not that skilled to make one myself! Thanks!
