Marc by Marc Jacobs Field Bag

Next time I'm out in the field (and when I say 'out in the field' I mean 'shopping on Oxford Street', because let's face it, at this time of year it's a blood sport) I'd quite like the Marc by Marc Jacobs 'Field Bag' on my shoulder. Like a funked up version of my dad's old camcorder bag, this little number will hold all those shopping essentials (purse, phone, pop socks for trying on shoes, smelling salts for when I faint at the price, large blunt object for poking shopping rivals...) and leave room to stash those secret purchases that aren't Christmas pressies for other people. The bag is £225 at Accessories Lounge.
