This is All In Your Head.
I shop with panniers, and I do not let anyone pack my panniers. Bread on the bottom, all the weight on one side? No thanks. I wheel my cart out of the store, clip my panniers to the cart, load them, and take the cart back to the storage area. Then I ride home and it is no stress. if people think i look weird packing my bags, they probably think i look weird anyway ... and frankly i don't care.
if for some reason only clipping bags to your body is the only acceptable solution---and That won't look weird, no way----then get some two- or three-inch webbing, make a belt and suspenders and chest and back straps and sew on loops for your carabiners. No stress and you say you have done it before. With the ready availability of quick-release buckles, you could have every strap abler to unclip independently, so you could take the harness off easily in any space and with any load.
Whatever.
