Silk is a delicate & usually a semi-transparent fabric, and a french seam would seem to be preferable to an open seam because silk does fray and the raw edges would need to be finished. Would this addition process add bulk and drag on the drape of the fabric?

I would also like to know how a french seam affects sewing & bulk around the armhole and how the french seam is done around this area where the side & armhole seams intersect.

thank you

Yes, French seams add a little bulk. But consider our blue jeans which have lengthy French seams, and are not too bulky.

You will find additional information, including intersecting French seams in these sites.
