HA! That is really funny.
Today I was wearing a longer shirt around the house and it does seem to help. I know I look sloppy but at least my gun won't peek out everytime I bend over.
I have a holster that slides down in the back of my jeans, it has a metal clip that is on the outside over my belt.
I tuck the tail of my Tshirt up under the clip, and it keeps my Tshirt from riding up.
I carry a Springfield XDM with no problem.

do what MAD says
don't bent over to pick things up
squat down to pick things up
