dance party

I saw a ballroom dancing party at a hotel on the 2nd of July. I've watched a movie about the kinds of dance ,but I was in the same room at the night.
One of my friends dances well, and we requested her that my friends and I could see her dance,and finally we got the chance.
The group of the members had a party and we could join the party.When we opened the door,I knew it was like one of the movies scenes.They all women were wearing the pretty dresses and the men led the women.They look very happy.
The end of the party,we could see the show.My friend practices dancing everyday ,so she was so elegant,accuracy,and powerful,and I almost cried when I saw her.I took some photos.
