I just got my Clock dress from lady Sloth yesterday, and I just love it!
Lady Sloth is called 
xkahax here on LJ, and her Facebook page is called Lady Sloth.
I ordered the dress the week before Easter, so it took about 3 weeks from this time I ordered and got it in the post.
Quality/Construction:
The dress is not lined, but the fabric is pretty thick and heavy, so I don't really mind. i'm not sure what the fabric is made out of, but it kinda feels like a really thick cutsew fabric with less elastic.
The construction is absolutely gorgeous! All seems are straight, no loose threads and the back has shirring with plastic boning.
Fit: 5/4.5
It fits perfectly. I would maybe liked to have it a little shorter, but that's just personal preference.
Communication: 5/5
I had a little hard time deciding what to buy (they are all so pretty), but she was always quick and kind to answer.
I asked her if it was possible to have another kind of top on the dress, and sent her this picture. She told me it was possible and that she could do it without any extra costs!
Cost: 5/5
The dress cost $65, which is really really cheap considering the quality. I also asked for some custom changes, and she told there would be no extra cost.
Overall: 5/5
Everything was great and I love the dress. I saving up to buy more, because I'm definitely getting another piece from her!
