For IDPA, I use a Blade-Tech ladies offset drop holster. It's Kydex. Concealable under baggy shirts, vests or jackets. Not so easily with a dress, skirt and the like. But I LOVE it. My draw is much smoother and faster since I started using it vs a regular holster.
When I get my carry permit, I'll need to find an IWB holster of some sort, haven't had a chance to try any out yet. Good luck!
