Just wanted to let y'all know that I tried on the Cleo B44 knock off last night and unlike Jules, found the quality to be quite good. I didn't notice any shiny looser threads at all. In fact, I will be honest and say I thought the quality was actually better than the authentic Bailey 44 dress. The true B44 has raw edge finishing on the tiers and hem which is something I'm not overly keen on. To me, the uneven edge looks cheap. On the Cleo version, the hem of the dress and the lining are completely finished, as well as the hem of each tier. I like that. The fabric was heavier and the lining more substantial than the B44 so I do think the dress would be hotter in the summer though and the fabric was not quite as soft. Sleeeves were the perfect 3/4 length on me even though I'm petite. I also found that because the fabric was more weighty, it was less clingy and therefore less body con that the B44 - I instantly felt a bit more comfortable in it. The Cleo dress does have a slightly roomier fit than the B44 so if you're looking for true body con, you'll want to size down. But because I'm not inclined towards body con, I truly loved the dress and will be watching for it on Dresses 30% off day and picking it up.
Just my two cents worth...
