It seems like we should be past the point where there is any question about what is appropriate for dance attire in a worship setting. Every dance ministry does not have to fit into the cookie-cutter mode of garments, but there are some basic commonalities that will prevent major fallout. What works in the church setting may differ from what works outside on the sidewalk. The key is to honor God and respect the viewing audience so as not to hinder our efforts.
It does not matter which culture we are trying to portray in our dances. We must be mindful of the culture that we are ministering to. Our choice of garment should not be such a stumblingblock to the viewer. If we think globally, we would respect the values of a country when travelling for ministry as long as they do not violate the principles of the Word. This will allow us to minister to them in a way that can be understood. Showing bare midriffs and bulging breasts will surely cause a ripple in the worship setting. Visible bra straps for females and boxer short on males (yes, I have seen this more than once) will distract. We should take precautions to avoid this.
There remains the segment of dancers who "feel" like we should have liberty to wear whatever suits us best. I would invite these dancers to refer to the Bible for instructions and pray for revelation in this area. Overly large, non-flattering garments can be dangerous and impair movement. We do not have to go to extremes. Wisdom and understanding will eliminate much of the discussion in this area. We must think beyond ourselves, and consider that others are watching our every move.
Jeremiah 13:22 (NKJV)
And if you say in your heart, “Why have these things come upon me?” For the greatness of your iniquity Your skirts have been uncovered, Your heels made bare.
Ezekiel 16:8 (NKJV)
“When I passed by you again and looked upon you, indeed your time was the time of love; so I spread My wing over you and covered your nakedness. Yes, I swore an oath to you and entered into a covenant with you, and you became Mine,” says the Lord GOD.
2 Corinthians 5:2-4 (NKJV)
For in this we groan, earnestly desiring to be clothed with our habitation which is from heaven, if indeed, having been clothed, we shall not be found naked. For we who are in this tent groan, being burdened, not because we want to be unclothed, but further clothed, that mortality may be swallowed up by life.
Revelation 3:18 (NKJV)
I counsel you to buy from Me gold refined in the fire, that you may be rich; and white garments, that you may be clothed, that the shame of your nakedness may not be revealed; and anoint your eyes with eye salve, that you may see.
