IMO, the dress needs to go on the figure WITHOUT removing the arms. So Yunsil needs to make adjustments or add a feature to make that possible, regardless of what it is. Elastic on the rear? Snap? Velcro? Something. I consider this part of any really great scale part.
Even though I'm looking forward to getting it in hand, the ribs in the fabric still bother the hell out of me to no end. I know there's better fabric out there because I've seen it, and this is simply something I find absolutely inexcusable after such a long period. It is what it is and we're paying for the Yunsil name.
