I have two very full, ankle-length tiered skirts for dance. In my current group, black is verboten, so my black skirt gets very little use and has been starting literally to collect dust. My red skirt gets used regularly, but that still means a maximum of about once a month. I rarely wash them: I always have an under layer, which keeps the skirt away from skin; they’re linen and washing changes the finish; and they’re rather a bother to dry (definitely not going in the dryer!). Also, packing them in my trunk with my other (cotton) costume skirts would leave me with a wrinkled mess.
A garment bag like the ones I made recently (edges straight down from the ends of the hanger) wouldn’t work because of the fullness at the bottom of the skirt. They’re both 12m around the hem. I wanted the minimum of fabric around the hanger, but I needed more at the bottom so as not to squash the hem. I measured loosely around the hem of the skirt as it hangs on the hanger and came up with a measurement of roughly 45″/115cm. Around the top of the hanger plus a bit of ease worked out to 30″/76cm.
How then should I go about widening from 30″ to 45″? I took inspiration from my own skirts. I did a yoke piece with the smaller measurement and sewed on the bottom piece, controlling the (limited) fullness with pleats. Although I used knife pleats in these skirts, my non-costume skirts use inverted box pleats. I pinned the pieces and found that the fullness was easily controlled by a single set of inverted box pleats.
The length of the bag was again dictated by the width of the fabric. I put one selvage at the hem. Because of the yoke piece, I had a choice of whether to put the other selvage at the top edge or the yoke seam. I chose the latter, then used the selvage to self-bind the yoke seam.
