My beloved jacket needs replacing, please help!

[posey]

I have a fab (imo!) casual jacket. Brown floppy linen type in a sort of denim jacket cut. Sits about hip level. It is lovely, goes with all my regular day to day clothes, not too warm but good for spring to autumn and cooler summer days. But it is really faded now and wearing thin and has a couple of holes on the side seams. I got it in M&S in Per Una maybe 5 years ago.

I really need a similar replacement. Anyone feel like helping?
Thanks
