I find them annoying too. In fact, I wish the there would be somehow to obt out of the game adding randomness. Should be very easy to implement. I prefer "decorating" my sims from scratch rather the first having to remove extreme combinations of piercing, necklace and glasses. I never understood why EA think it's funny to suggest that a sim should wear glasses when they sleep. Especially not if that sim is not wearing glasses with any other outfits. I'm a bit surprised that these bad choices were not programmed out n away with.
OP; I normally click the red cross on the group icon for all facial accessories (I think it shows jewelries&socks). Clicking the red cross cleans accessories. But you must repeat it for each outfit category.
