I'll tell you about the new leggings I got at the weekend - they are bloody brilliant.
I always rate leggings from American Apparel, believe me I have tried loads of others. Anyway, found that they now do some called winter leggings. They are much thicker and warmer than normal leggings, in fact they are really thick. I love them and think I'll have to order more now in different colours! They are £30 but well worth it imo.
They are thick enough to disguise any wobbly top leg too 
Has anyone else tried these? Wore mine yesterday and didnt want to take them off I was so warm
