This has been underconstruction Tuesday - the skirt and some of the ties were found during thrifty shopping on Tuesday (along with my lovely yellow shoes!). So here is a photo of the 'before':

I didn't like the buttons, but used the off'centre split for my necktie insert. This time I unpicked all the ties, removed the tie shaping/stiffener piece, and pressed the remaining fabric flat. This gave a much softer, flowing fabric. So I didn't end up using all the ties in the above photo - I only needed 3. Here's the after photos:
The waist is adjustable again - this time I use a snap tape. The skirt I started off with was a 10 with a waist measurement of 33" (84cm). It is now adjustable between 31" & 34" (79cm and 86cm). I wish I knew someone who was a size 10 so I could see what it looks like on!
