I have a large Muberry Anthony and it's lasted really well, still looks quite new, but I do find it a bit boxy. I also have 2 Mulberry Morgan cross body bags and they're a nicer shape, softer, rounded but I don't think Mulberry make them anymore.
As you live in Shropshire, is it feasible for you to travel to Ludlow? There's a fabulous shop in Ludlow town centre, he makes all of the bags/purses/accessories. You can have a custom made bag to your own specification and it will cost less than Mulberry and it's made in England, which is important to some people, rather than pay top dollar for something that's been made in China.
I've bought quite a few things from Matt Fothergill over the years and I have never, ever been disappointed. The quality is outstanding www.mattfothergill.com
