Velveteen winter skirt from Jane Marple. I bought it secondhand and have only tried it on, didn't like the length on me. I think it's one of their older pieces but I couldn't find it on Lolibrary. It has a used feeling, the waist seams are a bit stressed, and one of the side seams has come apart a little bit near the hem of the skirt (3rd picture). It is nevertheless a very solidly made piece that I think will last for years to come. Waist ties are non-detachable, outer (velveteen) fabric is cotton and the lining is acetate.

Measurements (taken flat):
Waist: 32 cm
Length: Varies a bit since the waistband has a little dip in the front and the hem is scalloped, but around 47-51 cm

Please note that I am not an expert and allow for a slight error in measuring.
