Concealed carry is not about finding a pistol, or holster, that fits your style of dress... It's about SLIGHTLY modifying your style of dress to conceal your pistol and it doesn't mean one needs to wear fatigues or camo to carry concealed. My Concealed Carry Instructor was able to conceal at LEAST 5 different pistols (at the same time) within his 'Business Casual' attire.
There are multiple articles on the web dealing with dressing to conceal.
Here are a few Bullet Points:
* If you end up carrying IWB, as much as you don't want to, you will probably need to increase your pants by one waist size (Form Fit pants are out).
** If it's a "Tuckable" IWB holster, you need to learn to 'blouse' your shirt a bit. *If it's not a Tuckable, you may need to start wearing untucked Polos/T-shirts made of thicker/heavier (non form fitting/tailored/clingy) material.
* Heavier material doesn't print like light/clingy/form fit shirt material
* Dark Color shirts hide printing better than light colors.
** Prints hide better than solids (like camouflage distorts hard lines).
** Untucked shirt tails need to be long enough to still cover when you reach for something up on the top shelf, or bend over to grab something from the bottom shelf. (of course... Reaching with your 'off' arm and stooping, rather than bending helps

)
Wherever on your body you decide to carry, you need to NOT be self-conscious about it.
* People acting self-conscious gets them 'Made' more than printing.
* People don't actually LOOK for printing, but they DO notice people who act self-conscious.
Take a oncealed carry course and maybe your instructor will give you some good tips as well.
