This bias cut denim skirt gets a lot of wear because it's a perfect partner for my work wardrobe - casual but with a twist. In winter, I often combined it with this jacket and brown boots. The pattern is self drafted based on my A-skirt sloper that I use for all my skirts. The back looks a bit weird in the pictures because my derrière is a bit curvier than the one of my dress form:-)
Just a note on sewing denim on the bias: I reinforced the center seams with fusible stay tape to avoid bubbling after topstitching. And I fully lined the skirt, cutting the lining on the straight grain. With these measures, the skirt has kept it's shape pretty well.
