In the photo above you can see the flare taking shape — it’s the part of the skirt that is meant to look like the top of a marble bag flaring out above a cinched tie cord. The yellow cinch cord goes on last.
The real bags didn’t flare. The tie was in a sleeve at the top, but I prefer this look; I’ve taken some artistic license. I’ll flock the whole thing in the same colour purple and then I’ll add the logo and the cords. I’ve lots more to do, but you can really see this dress shaping up now.
