My wife uses a Blackhawk fanny pack mostly, but she has a few very nice inside the waistband rigs. There are a few places that make holster specifically for women, but i can't remember who right off the top of my head. Don't use a holster purse if you don't have to - off body carry leaves too many openings to be "relieved"of your sidearm.
A good belt is a must, czech out the High Noon Rock Steady, as they can come in narrower sizes, and offer embossing to look like snakeskin, ostrich, and I think a few others, so not to appear like you borrowed somebody's work belt. Of course, that does limit the clothes you can wear. What sidearm are you carrying?
