Clothing is important. I carry full size guns. Usually on a belt instead of IWB. Summer I wear if i choose to conceal a 5.11 vest and t-shirt. Fall usually a large sweatshirt that is bulky or sweater. Winter a coat. You can also find shirts for spring and summer that are slightly larger in order to conceal. Crossbreed holsters has some great IWB holsters. With the right clothes and what you carry it can make all the difference. In Wash. State open carry is legal even without a permit so we have that option. I do have a permit so winter makes it easier to carry concealed.
