My Mum has asked me for a cotton jumper this Christmas and I'm struggling and don't have the time to browse lots of websites or go shopping! I've searched John Lewis and M&S but couldn't find what I was after 
She would like a plain, neutral coloured natural fabric jumper with a high neckline, long sleeves and no fuss or embelishments. The sort that you would use to wear under a jacket etc.
Has anyone any ideas? M&S were selling thr perfect thing in a range of colours but in viscose which she vehemently opposes.
