Leg Avenuewomens Layered Tulle Petticoat Costume Accessories (pack of 1)

Has anyone tried to actually wear it as a petticoat, under another skirt?

how long is this petticoat?

I am a petite 4'11", waist size about 25.5". Will the elastic waist fit or be too big?

my waist is about 39 inches and im 190 pounds do i get a one size or 1x/2x?
