Carrying a firearm concealed is not really a one-size-fits-all scenario. If all you have to be concerned about is covering, versus concealing, then the problem is easier solved. Most, however, prefer actual concealment versus merely covering the tell-tale lump of a firearm.
Pocket carry, like carrying in any manner, requires getting used to having the firearm on your person. That is one reason LE academies require students to carry red-handle firearms at all times. It allows them to get used to carrying.
For pocket carry to work, you must wear loose-fitting clothing, and you must be prepared to buy "relaxed fit" in everything so that the extra room can be used to accommodate the firearm.
Levi "pockets" are simply not as deep as required for any type of pocket carry. An LCP/Bodyguard .380 will fit, but not comfortably when you sit down due to where the "bend" is in relation to the pistol. Any larger pistol in Levi brand jeans is too long, regardless of the sitting/bend issue.
Effective pocket carry will require jeans with deeper pockets, if there is such a thing, or some other type of pants. Fortunately, 5.11s as well as Dockers or other types of khakis (whether blue or tan) are tough enough for casual wear and they don't look bad either. Those have pockets sufficient to support the weight of the pistol. Remember that a proper belt is still required, and you have to cinch it up enough to offset the weight of the firearm. That takes some getting used to, but it helps in preventing the pants from riding down under the weight of your pistol.
If you insist on wearing your pants "skin tight" to show your "assets," whether front or back, then obviously, carrying a firearm is secondary to your need for approval, and that presents a whole other set of issues.
