Recently I bought a grey long cardigan. It fits my rule of longevity in that I can see myself wearing it in 10 years. I think I can confidently say this as I have a navy cardigan from Primark that I bought about 8 years ago and it is still going strong. A feature I particularly like of my navy cardigan is the baggy pocket. It adds a bit of oomph to what could be a boring functional addition.
My new grey cardigan has the same baggy low down pockets. I am delighted.
(you can see I a more comfortable on the posing front nowadays).
This cardigan is in stock in my local store but I cannot find a link on line.
