Sakeneko, that's what I'm thinking now that I have enough blood sugar to think this through. If they had a cleavage holster, I could just about hide that little Ruger in there. I'm looking at the belly holster. How'd you get the custom stuff made?
The "custom stuff" I have is a holster that is custom-made to fit my gun, not a bra-holster or suchlike. I got mine from Rob Leahy at Simply Rugged (
http://www.simplyrugged.com); it's the "Silver Dollar pancake holster". Then, I bought a bellyband separately, to which I attach the holster using sewn-on tough/industrial strength velcro strips. I also added some strong velcro fastenings to a sturdy, but quite normal, support bra that fits me well. That gives me two methods of carry that both work well, albeit with different clothing and in different circumstances, while using the same custom-fit holster.
I wear the bellyband the most, with the gun almost directly under my arm and above the waistline. The grip of my S&W Model 60 hides nicely in the hollow against my side and is invisible unless I'm wearing a tight top. (Rare, in my case; my usual style tends towards modest, with comfort taking precedence.) It's also *very* easy to retrieve and shoot from that angle; I practice rapid draw-and-shoot when I'm training.
When I'm wearing a tighter top, even one with a low neckline, I switch to the bra carry. I'm not Vegas-stacked by any means, but with bra carry the gun is completely invisible under most of my dressy tops and dresses. Unless the neckline is extremely high and tight (again, rare in my case), it's also easy to draw the gun if I need it.
I don't know if these methods will work well for you. Somebody who is thinner/has a narrow waistline will probably find it easier to hide the gun along the waistline than I do. And a friend of mine who is fairly flat up top can't do what I do at all. The "secret" to good concealed carry is experimentation, because the "right" answer tends to be different for each person. If you can afford the time and money, I'd suggest trying out several methods.
