I enjoy making variations on the same pattern, especially when its worked well for me before.
I've used New Look 6216 trousers lots of times now, with some minor alterations for my full seat.
First I made some trousers from some duck egg blue cotton sheeting. These are made as per the pattern, except I have added a working elastic/drawstring waist, so the waist is truly adjustable. (The pattern has a full elastic waist and a non functional tie sewn on) Given the very casual nature these are being used as PJ trousers.
