If the standards are biblical, then they are a part of our obedience and consecration to God, period. Just as it is necessary to walk victoriously over bitterness, envy, lying, lasciviousness, etc. If we are holy, then we are holy in ALL manner of conversation.
Matthew 23:26 (KJV) [Thou] blind Pharisee, cleanse first that [which is] within the cup and platter, that the outside of them may be clean also.
Sisters cutting their hair and wearing jewelry aren’t holy. Brothers lying and telling/laughing at lewd jokes aren’t holy.
