Dressmaking advice needed

[Tybee]

So, DD and I had a work session last night. We sketched the design, and chose the fabrics from a pile of swatches she bought from Mood (Project Runway reference--it was so cool getting the swatches in a little Mood bag!).

For you guys who are familiar with fabric. She has chosen a 2-ply silk organza. I was planning on adding an underlining. My question:

Should I have her buy 4-ply rather than 2-ply? The skirt will be slightly gathered--not completely straight. She will have a shiffli embroidered tulle lace overlay. We don't want it to have much structure, but we also don't want it to be see-through. Will the 2-ply be enough, if it has the underlining + the tulle overlay?

I don't know anything about silks and plys, but I did find this thread that talks about the feel of the garment, and how that may impact what she wants?

Thank you!! This is helpful! These fabrics aren't cheap but I know nothing about them and I don't want to make an expensive mistake!

4 ply will be heavier and have more drape. Something like crepe de chine will be more lighter and more "billowy" if that makes sense.
