The idea of using skin colored fabric to cover more and give the illusion of showing skin is not new and I generally don’t mind it, especially if the color matches with the outfit too.
This is a great example. the blouse design could have been just the strings of crystal strings but by including the skin colored fabric, she achieved both looks. and the fact that the color goes well with the saree is an extra bonus.
I have seen this employed for faux strapless blouses too.
