For both the 62L/62LS and the 62C/62CS it has been suggested that, for additional concealment, some blousing of the wearer's shirt over the grips will hide the weapon completely, leaving only the loops or the clip visible. This works fine (see illustrations). Bear in mind, however, that any exaggerated movement to the side opposite from where the weapon is worn is bound to expose it -- unless, of course, you've taken to wearing your shirt bloused like some itinerant Cossack dancer, in which case most people will be far too busy admiring your fancy footwork to bother looking for a concealed weapon! If, however, you tend, like most folk, to dress normally, then I suggest a light bomber-jacket or similar garment. Today's fashion dictates that for casual wear the shirt be worn outside the trousers -- definitely a bonus for users of IWB holsters.

Some words of caution:
(1) Personal experience backed by customer feedback has shown that IWB carry for wide-bodied autos together with magazines can be an uncomfortable experience if used over prolonged periods of time. So if you own a Glock or similar weapon and are considering IWB carry, shove the weapon (unloaded) and a mag or two into your trouser waistband for a few hours and see how you cope with the discomfort quotient before you decide.
(2) Although 62L/62LS has a built-in variable rake facility because of the belt loop being screw-fastened to the holster, this rake may only be varied either way by no more than 20 or 25 degrees, this in order to ensure a personal preference for a comfortable draw. Some users are attempting to fix the loops to an extreme angle of rake and wear the holster in the small-of back position. I can personally guarantee that this will not work. Firstly, the holster will not retain an extreme angle, no matter how much you tighten the fixing screw and, secondly, if it did, the holstered weapon would almost certainly somersault out from inside the waistband at the first sign of any movement.
(3) 62C may be clip-fastening, but is NOT a solution to the myth of "beltless" carry. These holsters and mag-pouches MUST be worn with a belt in order to function efficiently.
