I'd recommend that she give a belly band a try. Find a 4" wide one...the wider 5" or 6" ones aren't as comfortable as the 4" ones. The wider ones are useful for carrying heavier guns as they distribute the weight better and don't "sag" down where the gun is....but for a gun as light as a Taurus .38 Titanium, the 4" would work very nicely and they're super comfortable. I carry my Taurus .38 Ultra-Lite in mine and I can hardly tell I have it on.
eBay is a good place to find several different brands and sizes of belly bands.....Pro-Tech Outdoors makes a decent one for around $20.
