I'm thinking I need a handy but stylish messenger style bag for the Autumn/Winter, as I have no hands free when pushing my two boys about in the buggy! Has anyone seen the Bay messenger style bag available anywhere in the UK? They call it the "sachel" on Chloe.com. Preferably in black. Is there anyone who owns this style that can give me advice about how big/heavy it is? Or any other ideas of bags that I can wear messenger style? Any advice would be appreciated!
