If you're looking for a trusty but eternally stylish satchel, there's only one place to go: The Cambridge Satchel Company.
Run by a mother and daughter team, Cambridge Satchel Co. have been producing quality satchels, in the classic British design, since 2008 (and they're a bit of a British business success story). And the best bit is, despite the gushing coverage across national magazines and the blogosphere, they've maintained utterly lovely customer service. Both satchels shown here are from the Classic range (£84 each for the 15" size). But if you're after something different, do take a look at the Fluoro and Metallic ranges.
On a similarly scholarly note (try saying that fast), did you know the Cambridge Satchel Company also sell properly lovely trunks? As with the satchels, they're available in a rainbow of colours and can be personalised too. There are 3 sizes - treasure, steamer and classic and as with the satchels, all are made in Great Britain. Top of my wish list is this yellow steamer trunk (£129.50):
Which colour would you pick?
