I am in love with this dress! What an achievement if I could make one. I tried to scour the net for patterns and lucky enough, I've found some.
Patterns below are from the ladies of Osinka website.
Vertical Front Band (bodice part)
More detailed pattern for the vertical front band
Openwork X stitch connecting the front band all around front to back
Bottom band from which I think where everything starts..
linking the upper portion of the skirt dress
H&M.. love this dress!
