Well, I am no expert on Fashion, or Dance clothing, or the like but I do know what the church teaches on modesty. “Because the way you dress sends messages about yourself to others and often influences the way you and others act, you should dress in such a way as to bring out the best in yourself and those around you." (For the Strength of Youth, Salt Lake City: The Church of Jesus Christ of Latter-day Saints, 1990, p. 8.) I remember teaching modesty to a group of 16 year old girls at EFY a couple of years ago. Our group name was "Shamefacedness" and we weren't even provided a scripture, but in personal scripture study one of the girls found the scripture that referanced our group name and taught me a little something as well. We had thought it had to do with modesty, but this added a new light. 2 Tim 2:9 9 In like manner also, that women adorn themselves in modest capparel, with shamefacedness and sobriety; not with broided hair, or gold, or pearls, or costly array; And right at the bottom of the page was the footnote saying it was from the Greek meaning modesty or reverence. Of course it makes sense that modesty and reverence would be related and somewhat interchangeable, but I had never really comtemplated the two together or as synonyms. The Lord gave us our bodies and we have the priveledge to use them and clothe them. We should remember that the clothes we wear reverence the gift we were given. I am afraid I cannot answer whether or not dancing costumes should have covered backs or if they can show off your hips, but I do know that the Lord gave us the guidelines for a reason. If we draw near unto Him, He will draw near unto us. Likewise, if we treat our bodies as the wonderous gift we have been given by the Lord, we will cover them in a suitable manner. I remember I was once told I should act as if the Savior could walk in the room at any moment. I believe the same goes for clothing our bodies. If you are clothing yourself in a way that you would be comfortable in the presence of the Savior, then you have nothing to worry about.
