When I wear tight tops, I tend to carry on my ankle. Most women's jeans have loose enough fitting legs that this works well, though a G19 is kinda large for an ankle gun. I usually carry my G26. I also have a Sig P239 that I carry IWB sometimes, depending on what I'm wearing, in a Comp-Tac. This works well for shorter shirts or sweaters, but still need to be loose enough to prevent printing. I have found that I'm not that crazy about IWB, unfortunately my hipbones have a tendency to try to push the holster up out of my pants. My last resort is a purse that was designed to conceal a gun, but I prefer to have the gun on my person. Experiment, find what works best for you. Sometimes you may have to choose whether you want to look trendy or you want to be able to carry. There are many options out there.
Age and treachery trumps youth and exuberance.
