I've been away from the community for a while and it seems that Sintiklia is only working now with Second Life stuff, since the download post on her tumblr gives me a 404 and searching on her tumblr for any sims-related posts only returned to me a post with SL stuff
Her blogspot blog redirects to the tumblr post mentioned above, and I also searched on TSR as well and found the dress only

So if you have an alternative link for the umbrellas/fan/poses that are included on this set...

Managed to find an older version of her post with the Wayback Machine, here are the non-Adfly links:

Dresses and chokers/neck accessories: https://drive.google.com/file/d/0B7...GoxVlJXQWs/edit
Umbrella: https://drive.google.com/file/d/0B7...nJxWWFQTkU/edit
Fan: http://www.mediafire.com/file/4e93h...ss+lace+fan.rar
Poses: http://www.mediafire.com/file/utu68...nd+umbrella.rar

Here's the original post with more preview images: Tumblr post, decoded the links with this URL decoder.

Wow, I never thought that was possible to use the Wayback Machine to do that!

Thank you :lovestruc
