Good to see you back Adelle. I've wondered where you have been.
One thing about "see-thru" clothing is so much depends on the lighting conditions. I think we all remember the photo of John Kerry's daughter wearing a dress which probably looked pretty opaque under normal light but turned (politically) embarrassing transparent under bright flashes from photographers. This typically happens when both the camera and light source are perpendicular to the fabric weave.
By the way- it wasn't quite this obvious- I raised and stretched the blacks a bit.
