The J frame is a great EDC choice, I carry a 640 as a bug and sometimes as my EDC. My wife's carry choice is a 642-1 nl and she uses an old Buchiemer holster at 4-4:30. My daughter and daughter-n-law carry a Glock 42 and Sig 938, respectively, appendix with inside the waist band holsters. You will have to work it out to see what works best for you. Check YouTube... there are several women that have channels that can help educate you and learn of their choices and how they found a way to carry a sidearm.

Good luck and congrats for being pro-active in defense of yourself and those close to you.
