replica or original design?

[dandelion-cloud.livejournal.com]

Hello ladies,

I just came across this dress design on taobao:



As a dancer, I'm totally in love with the design and it would look amazing with my Btssb Odette shoes in black! But since the manufacturer is known for making replicas, I wanted to ask whether this is an original design or a replica, and if it's a replica, where the original is from?

Many thanks in advance :)
