I’m 5’. I tried M&S heatgen leggings yesterday and although I’m a size 8/10, even their 6 was too high on waist, with spare material over stomach. Also way too long and felt like they’d get quickly out of shape. I got size 12 in their heatgen turtleneck tops which fit fine, so the sizing seems mad. I’d like leggings that fit are cosy, and that I can wear on their own with a jumper in milder weather or under jeans in really cold weather. Any recommendations really appreciated.
