Looks like a pretty simple adaptation of a sundress!
Your best bet is probably to make yourself a white sundress (maybe like variant A on this pattern?
), add a black waistband, and paint in the skirt lines/details. That bottom border could be a tricky piece to sew, because of all the curved pieces.
As for the top, you could also add your own spin to it! That's the awesome part of gijinka design.
