Well, I can't say that I ever thought about making denim leggings, let alone wearing them, but the French, black denim that I ordered from EmmaOneSock turned out to be much lighter and stretchier than I anticipated. It seemed destined for leggings.
When I told a friend that I was going to make denim leggings, she said that she had never heard of denim leggings. I said, "Haven't you seen all those ones on net-a-porter?" Her reply, "Net-a-what?". Hmm, must remember to keep internet trawling obsessions to self.
They look better than I expected. Perhaps fit really is flattering. If I get too thigh conscious, I can always save them for under my trench or perhaps even a dress.
To make them, I started with my jeans pattern. I decided to eliminate all the pockets and have an invisible side zip rather than a fly front. This was to keep it all sleek in the squidgy region. I placed my leggings pattern over the top and used it to shape the side seams. I wasn't sure how much extra width I would need, compared to the leggings pattern, so I kept to the leg width of the jeans, basted them together and then took in the side seams until I was happy with the fit. I put 25mm wide elastic in the waist band, to stop them falling down as they stretch with wearing. I did this by sewing the elastic to the wasitband seam allowance when I was understitching the wasitband, similar to the method you would use if using a grosgrain ribbon as a skirt facing.
In spite of these distractions, I am making progress with my couture dress. I have stitched most of the outer dress together. I just need to sew the side seams and then finish catchstitching all the seam allowances to the underlining. I'm not sure what to do about the hem. The method I am following attaches the lining to the hem with a jump, but I am not sure that this is the best thing for a flared skirt. The fabric frays. I guess overlocking is not very couture? I haven't started on the lining yet. I may have to take that away with me.
