Inside, there are black shorts and lining. The skirt is flared, so I could wear it with peace of mind knowing it has shorts underneath. The waist is elastic. Flat measurement without stretching the elastic: 33 cm. Stretched, it extends to about 54 cm. There are some pills on the elastic waistband. Initials are written on the tag. There is a stain or dirt?
