I made a No Nipples morph for the left and right collars which came out pretty well. Hopefully this will work for you. I'll put it in free stuff once I have some more morphs that I like, but here's just the nipple morphs in the meantime. (I do have some other morphs available in free stuff if you're interested.)

Cheers!
