White dance costume

I wore this a few times when I danced at church. The size it cut out of the leotard so I don't know the size. I have a very long torso and when I tried it on it really has to stretch. I was 12 or thirteen when I wore this and I was super tiny then so I would say it's an adult small. You have to be very decent when you dance at church so I also wore the white culottes underneath that are in the last picture.
