Its really not all that hard to conceal a full sized handgun or 2 on your average sized guy. Good holsters and good belts make a world of difference. You may have to change the way you dress a bit. Some people like to wear shorts and T shirts in the summer time which makes it harder to conceal weapons and does not really make you any more comfortable. Go look at how native desert people dress you can conceal ak-47s under that.
Also having your clothes tailored can make things easier. By that I mean taking your store bought clothes to a tailor not having custom made clothes. Its not to expensive your clothes will fit better too.
