ABS Allen B Schwartz skirt

I love this beautiful size 30 ABS denim with embroidery & beading skirt...I wore it a lot & there is a lot of beading missing, especially in back seat area but still such a beauty I would be keeping if it still fit me! It needs to be cleaned but was afraid too cuz of beads. Flat waist measurements are 16”1/2, length 35”.
