Q: Why is fashion decay a big deal?
[A] It affects our integrity of keeping our vow of a baptized eyes (including marriage vow) by fighting against our flesh desires (where adultry is committed just with our set desires of our eyes). (Matt 5:27,"But I say to you that whoever looks at a woman to lust for her has already committed adultery with her in his heart.")
[B] As long as I am happy, hey YOLO! It's not a big deal! Unbaptized eyes are not hurtful and if my man gazes at another woman lustfully, i wont get hurt. It dont matter what I dont want to be done to others be don on me.
[C] I don't know what you are talking about!
