Well I wouldn't lay down the law about this ....
Let's wear what we like and feel comfortable and confident for heaven's sake!!! Age is immaterial!!!!
I'm with JuJu on this one! I'm 61, short fairly slim but not skinny by any stretch, and wear all sorts of jeans and leggings (latter mainly under long tunics either tucked into boots in winter or cut off in spring/autumn), and mainly very fitted narrow jeans/canvas equivalents - are these skinny jeans? Maybe! Sometimes looser ones/cut-offs. I also wear shorts of all lengths in this weather and including very short ones! These come out at the first sign of sunshine in March (not to the supermarket

) but all the time when camping if hot and at home. Mine have to be low waisted to avoid the embarrassing lack of wasit and how it spills over (yuk!).
I will never be dictated to by anyone about what I should wear at my age, and trust my own judgement when it comes to fashion!
Let's grow old disgracefully and not worry about all of this.
Yes - naughty words....
