It's my mum's 70th at the end of November and I would like to get her a nice jumper. As I am returning to college this month money isn't too good. I have been looking at Uniglo (as recommended by many on mumsnet ) and like their simple styles. Can anyone advise me on their sizing? She is a big 12 to small 14 (a 12 in m&s) so would a medium be right for her? Many thanks.
