This dress is manufactured by HeartE, and the asking price is just over $1300 USD. It never specifically states that it is a wedding dress...but with the price tag and appearance, I don't think that's too much of a stretch. It is under the jumper-skirt category.
Wow O_OI expected it to be 100% silk or something, but it says polyster? That's crazy!(And congrats on first post XD)
Ah. If you look up close, you can see that the whole fabric looks like lace O_O Everything.Wow o.o
