EUC VTG Gucci Black Silk Maxi Skirt

I’m selling this Gucci skirt on my mom’s behalf. It’s been worn only once and in excellent condition. No flaws, stains, holes or wear except for the tag label for the skirt shell (label inside the slip lining is still there and photographed). Gorgeous silk mermaid maxi skirt. Smooth and rich silk with a cut that hugs your curves until it flares out at knee level. Very flattering and sexy silhouette. Skirt is lined with a rayon slip which hits right above the knees. The silk is a heavier gauge though, so the bottom half of the skirt is still opaque without the slip. This skirt has no stretch. It’s a US 6 but I would opine that it runs slightly small especially since the slip adds another layer and there are no slits. I think 2s and 4s can easily wear this piece. Top of skirt should sit right at the waistline and the bottom hits a little above the ankle. I’m having a really difficult time trying to find additional information about the year and collection this skirt is from and how to price it. My mom purchased this skirt sometime in the early 2000s. There is what appears to be a product number on the slip label but I’m having no luck online. Possibly 93 is the year this collection’s from? Gucci connoisseurs please advise.
