I'm in the market for a small messenger bag to use for travel, sightseeing, etc. I want it to be very casual and to go with any color (so something from LV with the vachetta leather would be perfect. I found a Gucci on their website that I like but it's a little too big. The LVs seem to be a little too small. It needs to be big enough for a small wallet, glasses and phone. Any suggestions where I can find one?
