This is for a brand new with tags Bench Women's Black Dance off + Halter Top Longsleeve Cotton Blend Shirt 

This shirt is a two for one. Comes with a long Sleeve Shirt with a Scoop neck with a very subtle hexagon design on the front panel of the shirt and a separate halter top to wear underneath.

I guess if your dance off really gets crazy you can simply take the long sleeve shirt off and continue in the halter top.
