IamSam I would be extremely interested in seeing your approach.
Sure, not a problem John.
Again, I did this really fast for demonstration purposes and I hope that others will slow down and take their time.
The technique assumes two things, the viewer will have some basic drawing skills and for pure ease, that you have a graphics tablet. I also want to point out that the example image that the OP posted is a digital painting by the virtual artist
Skip Staheli. This is why I felt that a painting technique would be most appropriate here but not the only one that could be used.
I opened a background photo and duplicated it. I renamed the duplicate layer 'background' (original I think).
On a new layer I titled 'Main Fabric layer',
I used the Pen Tool set to path for this step. I created a path that I can use as an 'outline'. If I had a subject in my image, I might have several paths fofr the CF (Chiffon Fabric) that interact with the subject, but for demonstration, I'll just use one simple path.
(note: I lowered the opacity of the background layer so you could see the path.)
I then turned the path into a selection.
I used the color picker to sample a light blue from the sky. I then adjusted the picked color to what I will call a blue/white.
I then filled the selection with the blue/white color and lowered it's opacity until it was sufficiently sheer. I made this one brighter for the demo.
I added a layer mask to this layer.
I create a new layer for the brush work.
I then activated the selection and the rest was done using the Brush Tool with various settings.
I also used the layer mask on the main fabric layer to increase the shear effect of the CF in certain places.
When I was done I created Stamp Visible layer (shift + option + command + E) and used the Blur Tool to blend the edges.
