Ok thanks everyone, I don't know much about Victorian dress or fashion in general. Had to google what a tie pin was

I know this is random, but does anyone know what is up with Johns little pom pom on his tie in the Christmas special trailer?? Its driving me insane!! like why are you there!?!? first its the random red thread on sherlock’s jacket and now this!?!? Whyyyyyyyyyyyy Im going to just assume its a couples thing and that Johnlock is now canon until another reason for the pom poms existence is presented... so, does anyone have an idea??
