I did have moments of thinking it looked a bit like a crocheted tablecloth from my 70's childhood, but now it is finished I am really pleased with it.
Instead of adding a waistband I fused a piece of stay tape to the top of the skirt, stitched on some grosgrain ribbon, folded it over and hand stitched it to the interlining.
The only other change I made was to peg in the hem a bit, I did my best to match the pattern at the side seams, but fit was a bigger priority so it isn't perfect, but definitely good enough as you can see from the photo of the seam on the inside above.
Despite the fact this is a lace skirt I think it will be wearable either dressed up or down. Here is the dressed up version - I wore the skirt last night to a Chinese wedding reception with a black silk jacket (Butterick 5186, now out of print - wow, I made this 5 years ago!) and a mint green necklace.
