Cheerleader outfit from the 1950s.  Skirt and shorts are fully lined.
The white lining has faded.  The turquoise color is still vibrant.
Measurements:
Chest 15.5"
Waist  14"
Length 39"
Handmade - no tags. 
I think it's probably a size 12.
Would have been worn with white top which is not included.

This is in very good shape.  I washed in washing machine and it came out very well.
It's fairly heavy with the lining.  Excellent seamstress.  It's a pretty blue/turquoise color.
