Have a look a Witt International, there are some leggings there that aren't the cling to your legs type, I used to be able to buy some leggings type trousers in Evans they were known as "easy pants", sadly they haven't done them for a while. Another nice site for long tops is Yours clothing I get quite a few things from there it might appear as a site for young people but while I'm not a grandma yet I am old enough to be one, both these companies have websites so it should be easy to find them. Oh, you could take a peek at 50 plus too also online. Happy hunting!
