Better to be judged by 12 than carried by 6, eh?
The least gun I have for carry is a Keltec .32.
It is about invisible in a pocket holster in my khakis.
Don't put anything in with it and get used to it so you don't pull it out inadvertently going for your keys.
There are bra holsters for women.

Look for Chick Gaylord's book Handgunner's Guide. He put holsters all over. He could go to a police convention, let a cop frisk him and still come up with one or more guns.
