Venizelos has convinced me it's not Set417, but for a similar reasons I doubt it's My Plaything (Set289/290/291/293) either. Yes, it's the same dress, but Silvia doesn't have platform shoes in My Plaything either.
However, I've now come to the conclusion misc_024 is related to Scene 6 from Skin Deep (Set298).
You can see Silvia is wearing that dress in set298_026, her hair is similar to misc_024, and there is a fleeting glimpse of her shoes in the movie: black platforms.
After Lewcoors's post in Spike's thread, I realized I have some upgraded scans from magazine High Society 2000/08. I renamed the pictures as if I prepared an upgrade for the catalog, but I never posted them here. Don't ask me why... it seems I totally ignore where I collected these scans and why I forgot to post them.
Many thanks for these great scans from High Society 2000/08, Adam.
As it happens I also had some PDF scans that I was working on, but much lower resolution than yours. The only slight improvement I have made was to edit out the "Dungeon 2000" banner and text from the first page, so possibly worth sharing here:
It would be nice if we could get a full-size scan of the cover with Silvia on it. The PDF I have unfortunately has an alternative cover showing Katja Kean.
Here's a very nice new photo for Set778 from the contents page of this magazine.
The scans I found are somewhat better overall quality than the ones I used for my previous restoration (see here), so I'll maybe revisit that when I have the time.
I just noticed that these four photos in the Viv Thomas 9264 "Foot Lovers' Close-Ups" set actually belong in Set322:
9264-06
9264-08
9264-10
9264-37
I initially wasn't sure, but what convinced me was the bracelet on the right wrist of "Enique" (aka Kylie) and the shape of her breast in 9264-10 definitely match other photos from the main set 3573. The pattern on the sheet and the headboard also match.
3573-22
Admittedly another esoteric addition to the catalogue.
