#1, What does it mean to be chaste?
Being chaste means respecting yourself and basically being sexually inactive. It means living in a way that God would want regarding human sexuality.
#2 How can I respect myself? And
You respect yourself by acting like a lady. You don’t give someone something just because they are nice, ask nicely or try and guilt you into it.
How you dress can be a reflection of how you feel about yourself. Do you dress (or act) in a way that demands special attention? Or are you happy with who you are?
#3, How does how I dress affect others?
I would say that in North America, most people probably dress with the weather in mind. Yet, there are people out there who will dress in such a manner to draw attention.
This can be good or bad.
The bad is obvious—women dressing inappropriately hoping guys will notice (we do, trust me). But also if you are an older kid, younger kids look up to that kind of stuff and may want to emulate that same behaviour.
But it doesn’t have to be bad.
Some people with social anxiety are told to wear an odd necklace or something like that so that a person will notice, comment on it, and start a conversation.
