ahh. XD
I still need to actually get the fabric(I thought we had it, but it turns out that the color is slightly off), and estimate the yardage being about... seven or so. I'm looking up patterns (my mom has a ton) to see if she has any that are close and can be altered. If not, I'm going to go and search simplicity, vogue, and butterick websites, then buy it. It's a very simple dress, the only problem could be the puffy sleeves... though there is a technique to make them...
The rest of it is a simple dress with a bell-shaped lower half. Under it would be a skirt of netting, from what the screenshots look like. It's also gothic lolita-themed, and it's not that hard to make a simple gothic lolita dress. When I find a good pattern, I'll post it up here, okay?
The socks are easy enough to find, as well. Here's a good site, but any store will probably have something.
