Clearly, toiles are going to be my friend.
The other thing is the guy who is helping them choreograph their wedding dance lives in Canberra. I also dance the style of dance, so seems I needed a practice skirt as well.
D's practice skirt is made from a thin satin, lined with a heavy calico. I put in a self-cover button pick up at the back, to allow her to dance. Trains and dancing do not get along.
My version of the dress is a slightly thicker satin, again lined with heavy calico.
