To a J-dub, the most important thing is "keeping up appearances". You always must look righteous.
Isn't that the truth (pun intended)
A JW friend of mine and I were discussing the concept of individual conscience v. dogmatic rules and she was telling me how the WT allowed individual dubs to freely make decisions about their lives where there was no clear biblical prohibition against their actions. She was saying that smoking was clearly defiling your Jehovah-created body by introducing foreign substances into it for selfish pleasure, and therefore unacceptable.
I then asked her if her relatively new breast implants, which were made of foreign substances that were introduced into her body purely for selfish pleasure, fell under that same rule. Without missing a beat she shook her head and said "Yes, but no one knows about those." It was as if they were perfectly fine with Jehovah, regardless of what the WT party line was, if no one in the congregation knew she had them. I tried to point out the fallacy in what she was saying, and she just kept repeating that they didn't know about her implants, and so it didn't matter what the WT position on them was.
It was a very surreal conversation.
