I think there are more ready-to-wear designers who don't have a solid grounding in fabric these days. As evidence, I present this skirt, which was cut in panels, out of stretch fabric, on the bias. Bias? Yes, please. Stretch? Well, ok, I guess, if we have to. Bias cut stretch fabric? Whoa, baby, way too much. Which made the front of this skirt poochy.
Nobody needs a poochy belly.
So I stabilized the front two panels of the skirt with silk (?*) organza and fusible interfacing.
I traced the shape I needed with pattern-trace (a type of soft paper used for making pattern pieces), then cut it out fusible and the organza. I sew the two pieces right-side to wrong side so that the fusing face of the fusible would be on the outside when I was done, leaving the bottom end unsewn, and turned it. Then I serged the bottom edge. Fused it in place, top stitched on the front as best I could, sometimes able to hide the stitching, sometimes not. (What's visible around the fly will mostly be disguised by clothing and nobody should be starting that hard at my crotch, anyway... )
Seriously. The whole point of ready-to-wear clothing is that it's READY TO WEAR. I should not have to correct design flaws born out of ignorance about fabric stretch and recovery, especially for brand-names usually known for decent quality. (This is an Eddie Bauer skirt.)
*I have a question mark here because neither I nor my mother can identify the fabric. It's from her stash, and previously from her mother's stash. It's stiff. Really stiff. It's sheer. It has only minimal stretch across the grain and zero along the grain. It kind of feels a bit like cotton, but I don't know how cotton could be stiff like this. If you wash it, it wrinkles madly and... maintains its hand. It kind of reminds me of the silk organza that is sometime used for interfacing or interlining, except it doesn't really seem like silk. Near as I can figure is that it's some very old form of interfacing from before the era of fusibles. Except that there were a couple different colors in Grandma's stash and why would interfacing come in different colors? Anyway. It's absolutely perfect for stuff like this.
