I don't always wear a belt, so I routinely carry items in my pockets. (I admit that I carry much less than many folks here, though.)

When I lived in FL I used the "belly band" and similar devices to carry a small SIG .380. (It's tough to conceal anything larger under a T shirt and shorts.) It would definately work for your EDC, but it's not very comfortable (the word "girdle" comes to mind).

I should also add that I haven't had the "pants falling down" issue, but YMMV.

Another option is to carry less stuff. (Yeah, I hate that option, too.)
