Consider a 16" key strap for her to carry it with. I keep mine on my SE at all times, so I can grab it out of other larger bags, and also so I can stick it over my shoulder as needed (it is very short for this use but works for me). I only use the long cross body strap rarely, as I usually need a big bag and the SE goes inside everything. But on a run into the grocery store, or whatever, I just grab out the SE, and hand or shoulder carry with the 16" connected to the two outside O-rings where a long strap would go. I also clip the carbiner on my keyring to this strap.
