Canon 13
About anathema to women who wear men's clothing for the sake of imaginary asceticism.
If a woman, for the sake of imaginary asceticism, changes her clothes and puts on men’s clothes instead of ordinary women’s clothes, let her be anathema.
Greek original
Εἴ τις γυνὴ διὰ νομιζομένην ἄσκησιν μεταβάλλοιτο ἀμφίασμα, καὶ ἀντὶ τοῦ εἰωθότος γυναικείου ἀμφιάσματος ἀνδρῷον ἀναλάβοι, ἀνάθεμα ἔστω.
