Valentino Red A-Line Belted Skirt Cotton 8 Gold

Valentino Red A-Line Belted Skirt Cotton 8 Gold Made in Italy in what feels and looks like cotton no stretch. Unlined. Matching ribbon fabric backed belt. The side pockets and hem are trimmed in real leather. There are no size or fabric labels. It fits big on my size 4-6 dress form so I am guessing it is a size 8. Please compare the actual measurements to a skirt you have that fits. The waist is 31 and the length in 18. Pre-owned in excellent condition with no flaws seen.
