FWIW the owner of my LDS is a woman of nearly identical stature to your wife. While she's had the chance to use MANY BCD's out there (not a BPW person) she always travels with her Aqualung Lotus. You might notice from the picture hers is a previous model that had the i3 inflation system, they've discontinued that feature but still make it with a standard shoulder inflator.

AL discontinued the i3? That’s fabulous news.
