Reddit mentions of Perry Suspender Men's 1.5" Elastic Original Adjustable Suspenders (Black)

Unbeatable fat guy carry system:

A Wilderness Instructor or other "gun belt." I held off on this for awhile wondering how much of a different a gun belt makes. I carry a light little Glock 26.

It makes a big difference. Like, huge. The belt can literally be used for emergency evaculation and can hold thousands of pounds. But it can be worn as a normal day to day belt as well, right through your belt loops. It will cost a bit but this is something you'll potentially have and use for decades. At some point is might even come in handy for MacGyver stuff, given its strength.

Then what you do is you get yourself some Perry suspenders. These are suspenders that clip onto the belt itself, rather than onto your pants. Together, you could probably carry as much weight as you want on your belt. Positive side-effect is it eliminates ass crackage when you bend over.

Then you throw on an unbuttoned button-down overshirt of some sort - flannel or cotton or whatever.

What I like about this is it enables me to carry as much weight as I need - flashlight, full leatherman, extra mags, without it being an issue.

As for holsters, I use a Bianchi accu-mold OWB holster which rides up high on my side, but my overshirt conceals it. But with this setup you could use anything you want. You can also carry the heaviest gun you want without it pulling your pants down.
