As you asked for opinions, I will offer mine. The jacket definitely looks pieced-together, although whomever did this apparently knows quite a bit about small details like the type of thread often used by Vietnamese & other Asian sew-shops. What strikes me as most indicative of a pieced-together uniform is the mixture of brand new and used insignia. The CIB, parachute wings & chevrons seem to have some light fading and wear to them, whereas the name tag and SSI look brand new. I am also a little skeptical that your SSI & Airborne tab are even originals, as I have seen reproductions with those colored backings. Early originals used khaki cloth as the base for the embroidery, although I have seen some originals using the same color cloth as the base of the embroidery (i.e. black or teal). The only way to tell for sure would be to remove the patch and look at the back.
On the plus side, at least everything has been placed properly.
