Vintage Handmade Polka Dot Skirt

Such a really cute retro handmade polka dot skirt. Has an elastic waste that stretches out to 17" and as seen in picture has thread all bunched up... I'm afraid to cut it as I'm not very good at sewing.. I'll leave that to someone who knows how... or honestly you don't really see it anyway. Also there is a faint stain in the picture I circled... believe me it's really faint!!

Length of skirt is 31"
