I am searching for the holy grail handbag for work. I plan to use it all the time so it will certainly get plenty of wear and needs to be able to stand up to commuting etc. I saw this on the John Lewis website from their own brand John Lewis Collection. Anyone know what quality/durability is like? I am in the US so will have to pay for shipping and returns if I don't like it so I'm not keen to go ahead unless I'm more certain what it'll be like.
