I tried on a number of pairs in different sizes and styles in Gap that didn't even make it over my calves, let alone any higher. If I did manage to get them on, the material still 'stuck' around the calf area and so didn't make it far enough up to fasten.
I'm 5'10", size 8-10 on top and 10-12 below and have calves in proportion to my height - no-one would remark that they are chunky but clearly they must be bigger than average.
Any ideas - apart from bootleg jeans.
