I have a concealed carry permit. please no anti-gun comments they are not necessary nor are the helpful.

I am starting a new job and will be wearing a suit everyday. What is the best way to concealed carry in a suit. I will not be in the jacket all day so it has to be more concealed the simply under the jacket.

I need to conceal a subcompact pistol. It is a Ruger LCP .380

Right now I am trying out/using an ankle holster but would prefer a more readily reachable location. Such as some form of under arm or behind back conceal.

It can not show when I am not wearing the jacket or be overly restrictive. What do you suggest? I also am trying to stay away from belt/in waistband holsters (unless you know are a very comfortable/non restrictive one). What do you think?

What do you suggest.

Run down:
conceal a subcompact pistol (Ruger LCP)
In a shirt in tie (under the dress shirt)
as non restrictive as possible
preferably not ankle or in waist concealment.
