I used this simplicity pattern minus the slit. I didn't want a slit. I cut a size 12 and it fit just right. Warning there is no, I mean no lining. So I had to come up with something, more to come.
I spray starched the chiffon and this helped a lot. It made it stiffer but the more you handled the chiffon the more floppy again. I used all the weight I could to keep the chiffon from shifting while I cut it. Because it will happen. That is the joy of sewing with chiffon. Something that will help you is a new blade on your rotary cutter.
Here some pictures while sewing.
As you can see I serged everything. Or else there would have been thread everywhere. The pattern did not address this at all. Now to make a lining. I had enough of fabric to make another layer. I just cut a big square the size of the fabric width. About the same length of the skirt. I sewed it together and added an elastic band to make a waist. I did a quick invisible zipper on the outer layer.
To hem the bottom I did a rolled hem but I had to adjust the ratio for the differential feed. Instead of 1, I did a 0.75 which then made the hem straight and not wavy as seen in the picture below.
Here is my skirt. I moderately like it. I feel the underskirt is too bulky and adds just a smidge of extra width to my hips. And it is still too sheery for my taste so I added a slip. I may just wear the slip only with the skirt for the future now thinking of it.
But I do like the way the skirt is- length is good. I like the upper band so again it doesn't add much thickness to my hips. I am going to try again with some more chiffon and add a lining! Stay tuned, coming soon!
