Ladies- I need some help. I thought there was just one Besace model, the messenger style with the flap. Is there more than one model? If I said I wanted Besace to a Bal SA, which one would they automatically give me? I want the messenger style one, which I thought was the only Besace. Any help would be appreciated. Would you get a besace or a courier? I want something easy (already have work, days, twiggies) that I can throw on over my coat and sweaters that closes (no wandering hands looking for my wallet). Any thoughts? Thank you in advance!
