I cut out and started to sew up the skirt from the Wardrobe pattern I like the most right now. Butterick B4295 which I bought when it was featured a couple of years ago in the magazine.
I reckon it can either become one of the SWAP advance pieces or just an 'extra' if I find I want to include other things as the advance pieces instead.
Changes so far:-
Cutting it 3 inches shorter than the long length skirt, adding a waist facing instead of their ribbon treatment and having three slim darts in the back instead of one large one.
The plan is to construct it as per the threads article on sewing for losing weight, so I can take the side seams in as I get slimmer.
