|I love to wear corduroy skirts and I have made some corduroy dresses for my daughter too. What I have learnt is that 100% cotton non-stretch corduroy makes much nicer, better draping skirts and dresses than stretch corduroy. The stretch fabric often seems thicker and plusher but it just doesn't drape which you really need it too.
Compare these three Muriel farbenmix dresses in the linked photo above. The dark red dress, while very plush and velvety looking really sticks out when worn and is very stiff. The floral print dress is non-stretch and drapes well, which looks much better on.
Compare these two very similar skirts:
Simplicity 4188 in stretch corduroy was a total wadder.
McCall 5429 in non-stretch corduroy is a joy to wear.
I have learnt this the hard way. So if you want successful corduroy skirts and dresses, forget the stretch!
