Whenever possible, though, she really ought to carry on body. If someone snatches her purse, she loses her gun. When carrying in her purse, she should put the strap over her head so it runs across her body, not just over her shoulder, to help prevent it being snatched.
My wife has taken some of her most favorite purses to a tailor and had them altered to have an extra pocket added. When she started carrying she didn't find a single style that she liked but after a little research found someone that would alter some of her purses that she already owned and has had some of her new ones altered as well. She can now get the fashionable purses that she wants AND can get her CC to be carried correctly in the purse without just flopping around.
