Choosing to dress modestly
I'm going through this journey too. It happened after a tragedy in my life, and the overwhelming sense hypocricy in my own life and a disconnect between what's acceptable on Sunday at church vs. what's acceptable other places.
I agree, bathing suits are like underwear, and many clothes options nowdays are like undergarments (tight tops etc.). It's hard for me to understand why as Christians we are so disconnected from God's view in this area. Yes, it hasn't been that long that bakini's have been considered appropriate swimwear, but long enough for us to forget and accept the current culture over God's standards for us. The people closest to me don't understand what I'm going through, or think it has relevance to them.
Choosing to dress modestly is good for me, good for others, pleases God, and makes me feel closer to God's will for my life. I wish I would have had this "revelation" earlier, or that I would have listened to God's spirit, which went from quiet to really loud in my life. The family of "19 Kids and Counting" also provided me with some encouragement, as well as Dannah Gresh, who is so graceful and an excellent teacher (has blog, books, website, conferences, ministry to teens, wisdom and grace and a challenging testimony).
I do feel "out there", as I went shopping for a bathingsuit with a respected Christian friend, and she didn't see any problem with the teeny, tiny bakinis. Now that I'm married, I don't like going to places where I know woman and girls will be baring almost all in front of me and my spouse. It makes me feel less special to my husband etc. If I double dated with another couple and the couple came dressed in their swimwear, I would think it was innappropriate, as would underwear. I think guys should be equally more modest, instead of walking around bare chested, for multiple reasons.
So, to wrap it up, I appreciate you sharing your own story and quest, and pray for God's coninual guidence in your life!
