I don't follow some the reasoning and justifications for many of the opinions here. I have seen the ideas expressed that, upon becoming a Christian, the person claims to be 'convicted' to stop eating meat, to get away from the church [often Baptist] in which one was raised, to stop watching television, and other things. In the cases I have been in position to know, these things do not last; sometimes they may last for month, or even years, but the person does come to realize these are really childish things and with proper growth and maturity they can see and divide the spiritual from the physical, or from something just perceived as being spiritual. Wearing dresses or skirts, as opposed to pants, is rather expectedly a primary reaction in that way, simply because so many traditionalist churches are known to be rigid about clothing standards.
But it is, on the other hand, a valid point, that some of the reactive things people are known to do actually can help the person in that she (he) is seen having made changes, and therefore there is affirmation in some way. When we are 'convicted,' we want to do something and be affirmed. God does not look on the outside, but man does, and that can be both a point and counterpoint in this topic.
