Oh my! As soon as I think I've completed my item list, it turns out that I still managed to miss a bunch of items.
Your post got me thinking about the
collection of DS outfits thread that we have here and noticed that I completely missed the Curcuma and Gentian outfits. I really hope that I'll be able to find PDFs for those... Sadly I couldn't find these shoes in that list. Maybe they were part of a Fuschia outfit (I wouldn't be surprised if that was the case, haha).
Thanks for the information Tiramisu, I hope we'll be able to solve this mystery eventually. ^^
