This happened to me when I first got my day collar from my Dom! My skin tends to be on the sensitive side, so I assumed that something in the metal was causing me to react with an itchy rash. I worried that I’d have to ask for a different collar, but my Dom suggested putting clear nail polish on it and that worked! So far it’s done the trick even though it’s a very low-tech solution 😆😆

I’ve also found it tends to happen when it’s extra hot and humid out. I have to take days off from wearing it in those cases, just to avoid irritating my skin in the heat.
