I don't really have anything that would work well really, but I did find these.
This might work for shot with the trousers, but this was literally the only thing I could find that would go with trousers!
I'm not sure which shot this would look best in, perhaps the cafe shot. Again, clothes wise I don't have anything.
These loafers could look really cute on the balloon/bike picture or the predominantly male picture.
Again, these would also be okay for the shots I mentioned above!
