Why choose a loose tank top?
A loose, light outfit is often a good choice for modern jazz and contemporary dance so that your movements can be seen more easily. Opting for a loose tank top lets you comfortably move unhindered throughout your activity.
What should you wear for modern jazz and contemporary dance?
Generally, dance teachers don't require students to wear a particular outfit for modern jazz or contemporary. This leaves you free to choose whichever outfit best suits your personality. All the same, you need to make sure your movements are visible and your outfit is comfortable throughout your class.
