There are absolutely no labels at all on either. There's a metal YKK zipper on the side of the blue dress and buttons up the back. The silver one also has buttons up the back and a very small plastic/nylon YKK zipper below the waist. Even tho there are buttonholes for the back buttons on the silver one, on the sleeves there is just loops and no buttonhole. The construction is as I've seen on older garments which is the strange thing ie bound hem on the blue one, rolled hem or double hem on the silver one and no overlocking to be seen. Oh and the buttons even though they are both covered in the same fabric have PRYM PATENTED underneath. As for fabrics, I'm sorry but I'm hopeless there...my friend used to work in a fashion house, so I'm gonna hv to meet up very soon and ask her for a crash course in fabrics!!!!
