I feel your pain, bro. A suggestion here …
First, make a cost/benefit decision on whether you will carry nor not. Personally, I would probably carry.
If YOUR answer is also that you will carry, then do a second cost/benefit analysis on which direction and how far you want to go between quick accessibility on one end and depth of concealment on the other. If I were going to carry in your situation, I would go way, way over toward the depth-of-concealment end of the scale – I’d want to just have the gun on me, and I would sacrifice as much accessibility as I needed to get the gun completely hidden.
I tried for quite awhile to find a carry system that works well for the limited purpose of just having a decent-power gun on me all day and have it utterly invisible. I'm talking about a deep-concealment, BUG. As an analogy, I wanted a way to carry that way as constantly and unnoticeable by me as carrying my wallet, which meant I'd put it on at the beginning of the day, keep it there all day, not feel it there all day, and not have my pocket capacity diminished by it all day. For this system (not generally), reasonably quick access was desired but not a premium concern, since my purpose was to just have it on me and THOROUGLY concealed.
I have carried concealed handguns for many years, and I suppose I've tried as many different options and configurations as the next guy. My most common carry methods are pocket holster and IWB, tuckable and not. Thankfully, I'm large enough to have carried a holstered P220 holstered in my front pocket (believe it or not), and between the time that I sold my Springfield Micro and when my CombatMaster arrive and passed my break-in tests, I even carried a LTW Commander that way, as long as the pockets were deep enough, without it being obvious. Carrying in my pocket is great, except it leaves me with one less pocket to carry my other, non-defensive-junk in. Also, I suffered from that malady common to many and which some refer to as "The Gone Ass", meaning that on a sunny day, and with the sun in front of me, an observer can likely see my belt buckle from the back, and even a little weight can tend to drag my trou downward. In the case at hand, even a smaller holstered gun would likely draw attention.
So, what are the other options? Of course, there's the ankle holster. In Central Alabama, it is warm enough to wear shorts almost all year, and so that's not a constant option. Frankly, I have yet to find one that doesn't get visible when I sit, so that’s probably out for your purposes too. Frankly, the only use I still have for one is when I'm asleep in a hotel room.
So, then you have the belly bands. Personally, they either print, or they are uncomfortable - If I put them anywhere but at appendix, they print. If I put them at appendix, they are uncomfortable. No, I'm not fat, but I just continue to raise my eyebrow when even the most svelte, hard-bodied operator type tells me that he can stuff even an officer's model in at appendix and not have it mash something somewhere! Bottom line is that I can do it if I gotta, but I am always aware of its presence because it is, to me, uncomfortable. Also, in your case, you’ll always be subconsciously hiding it with your arm, and thereby drawing attention to it, and when you walk in to someone’s office, and that someone is sitting down, it’s right at their eye level.
So, then you have the Thunderwear type stuff, and that has never been even reasonably comfortable for me - at the very least, I have had to "adjust" myself like some jock football player every time I sat down, and in the end, I moved the Thunderwear up so that it went around the top of my abdomen to make it more comfortable, but then had to keep pulling it back up all day.
The reason I mentioned all these that didn’t work for me is to lend credence (I hope) when I say that I have found something that works - for me at least - I can carry a CombatMaster, 9mm Kahr, etc. in a manner that is completely concealed, very positive (no slop), and unnoticeable to me - even without an undershirt under it. The rig is shown at the following web site:

This one is better than the one I originally bought in that this one’s straps do not come up around the neck where they are visible unless one wears a shirt with a buttoned collar.
This is basically an elastic, Velcro-closure, belly band but with suspender straps so that the belt is worn up under the armpits instead of at waist level. The weapon is in muzzle-down orientation, and I have found that carrying even a mid-sized pistol that way is almost like having a wallet - I put it on in the morning, it stays there all day, I don't feel it there all day, it doesn't take up room in my pockets I need for other things, it doesn't print, and it doesn't move, and so my daily activities don't have to be altered in any way. In fact, like my wallet, it gives me no reason to even notice that it's there.
The only real drawback is that drawing will probably be a bit slower than with IWB carry, but if I were in your situation, I could live with that.
I would think this would be a good option for you for the limited situation you are facing. It works very well for me, so I thought I’d pass it along.
Best,
Jon
