This skirt is from RONOVA - Indie brand based in Los Angeles.
I bought it in person from Anime Los Angeles few years ago.
I really loved this skirt but I want to down-size my closet for now.

it has bloomer inside and overall skirt is very fluffy.
so you can wear this by itself as skirt or wear this under skirt like petticoat.
I usually wear this under black dress. this is amazingly comfortable and fluffy.

Waist size is 23inch to 40 inch
Skirt length is 19inch (48cm)
