Dark colors are great for concealing the outline of your gun, so navy blue and black are especially good choices. Loose-fitting shirts are better than tight-fitting ones, and fabrics with patterns and prints such as stripes, flowers, animal prints, polka dots or squares can help distract the eye from any possible print of your firearm. You can also search for garments designed to be worn hidden in clothing, such as tactical t-shirts with built-in holsters. When you decide to carry a firearm, choose whatever you feel comfortable with and experiment at home with a mirror and various shirt styles to discover what works best for you.
Inside the waist covers are popular for hidden wear because they're easy to hide, so pants with belt loops will be ideal. Bandwidth covers for the navel or going with a company that makes leggings and specific running pants can make living a sports life very feasible. Reviewing your closet and trying on different outfits can help you get a better idea of what works with your hidden object lifestyle and what doesn't work. Whether you choose to wear it without a belt or not, your hidden carrying system is attached to your pants so it's not something you overlook.
While wearing it concealed is easier in pants, that doesn't mean it's not easy in other clothing styles as well.
