It is a holster but as I have found out in trying to market it, due to it being a one piece(hook and eye) that hygenic reasons prevent it from being returned if the customer does not like it so we will not be making and selling them. However, having worn it every day now, I can tell you that I am COMPLETELY happy with it and will share the design with anyone who is interested in making their own. It is ridiculously simple and can accommodate pretty much any drawing position(I keep it on right hip, slightly behind). Here are the pictures if you want to make one yourself.
Here is the finished product
Here is it is on...(please ignore that I am chunky and I ask that you not comment on that)
Playing with the position with safety pins to get it right.

Nearly invisible under a selection of clothes(although I mostly wear t-shirts)
Anyway, if any of you ladies would like to make your own, it is easy enough and doesn't take much time. I do have a frontal view but since it is a singlet and I wear my own bra with it, I do not want to advertise my front assets. If you know what I mean.
