I am currently on the website and it appears to be okay now. I am off work all this week and looking for another Mulberry bag (even though I bought another one three weeks ago!!!)
Thank goodness, spotted the new Mini Mabel in Marine at Harrods yesterday, but the SA was so unfriendly decided not to give them my money - so it's back to the website for me!
I have only seen the denim on the photo reference thread (I know someone has a denim mabel which I covet), marine is quite a harsh blue, a sort of subtle sapphire IRF.
I find the website is often slow and 'clunky' to use. I always hope it's because they're uploading sale details onto the site servers, but no luck so far..
