A vintage SUPER FULL crinoline petticoat (c. 1970's) made from blue nylon netting with a polyester hip yoke. This was probably a square dancing crinoline but is massively full and would suit being worn underneath a 1950's skirt.

It's in very good condition, the hip yoke has been cut down for a shorter height but all the fullness in the skirt is still there.
Waist measures 20" but can stretch to 35". Length is 21".
