If she is going to consider purse carry, I highly suggest she find a purse that can connect to her body in some way, so that it cant actually be taken away.
I use the wilderness safepacker, which rides on my belt just like a OWB holster, but looks kinda like a hip new purse stlye, whenever I really cant use my normal IWB holster.
Im sure there are purses out there that can both go over your should and around your waist, or over the shoulder and also snap to a belt. If not, you can retrofit one to do that.
