He was referring to the command in the Old Testament that bans wearing fabric blends. One thing to remember is that Jesus didn't nullify the law, he fulfilled the law. There were two types of rules in the Old Testament, ethical and lifestyle. There are a few instances in the New Testament where lifestyle rules are explicitly ignored without any condemnation for the actions (the opposite instead). The bleeding woman touching Jesus, Peter being told to eat unclean animals (meaning go talk to the Gentiles), and Paul telling the Galatians that the Gentiles do NOT need to be circumcised to be saved.

If one loves God and their neighbor, all the ethical law will be followed. One interesting loophole that Jesus removed was to love one another as He loved them (John 13:34) which is different than "Love your neighbor as yourself".
