CCW is like shoes. What works for some will not for others.
I'm spoiled insofar as I have lots of guns and lots of options. Open carry is legal here, "printing" is not a legal issue, and a gun on the belt -- even inside the waist band -- is not viewed as "concealed" with regard to requiring a CCW.
State law can affect how you carry.
I think by far the best option for a woman is in her purse -- dedicated purse with a pocket for the gun, which is not going to get snagged up in lipstick, combs, brushes, key rings, cell phones, etc.
I carry a portfolio a lot, people see me with it and so it's "normal dress." The gun's in the folio.
Carry needs to be appropriate. 90F and sunny, you're not going to "conceal" in a fur parka. Fanny pack will not work with a suit.
I've carried concealed everything from a Smith & Wesson 629, 4" bbl in 44 mag. -- which covered up fine. To a NAA Guardian semi-auto in 32 ACP, which was "too big" for what I was wearing.
Whatever you figure out, practice getting at the gun before you need to get at it.
