Pretty Dress

I have posted before on how some fans out there managed to notice about tiny errors. I don't think I am in the same shoe since noticing a tiny thing such as a pendant wore by actresses on screen was different with me noticing the same dress.

Above: Yoona's wearing it to the Baeksang Award.
Below: Sera's wearing it for her engagement party (sorry for the bad photo)

The question is, were they on strict budget or the designer was just trying to promote her/his work more?

What ever it is... the dress rock! I love it!! The colour, the design... it's beautiful. I prefer Yoo In Young (as Sera in My Precious Child) wearing it though.
