If you are a hard core dancer you dress to go dancing from your shoes up. The rest of what you wear needs to be comfortable, attractive, and stable (for some, strapless just isn't an option!) Attractive on the dance floor can be skin tight or floaty or a bit of both. The flirty skirt moves with the hips but don't forget the scarf option which also moves at your neck or in your hair.
By definition, silk scarves are dynamic and move with the slightest breeze so as you are whirling on the dance floor, your scarf whirls with you. A dramatic accent to add to your freestyle is to dance with the scarf, pulling it from your neck, flourishing it in time with the music, and languidly repositioning it on the next refrain.
