Do you wear fitting shirts? Do you wear shirts the way they are suppose to be worn? If so I don't think that you would have a problem wearing a hip holster. I only wear my shirts tucked in on very limited circumstances and have never had my shirt cover my weapon. If you are old enough to carry a firearm then I do think you can find a non resident concealed carry license/ permit. I think it is Maine that offers one for people over the age of 18.
I only wear a drop leg holster when I would have a hip holster covered. I have a carhartt jacket that would easily cover a hip holster, that is the only time I commonly wear a drop leg holster.
