I found this Versace shirt at a local thrift store. The color ...changes... in the light! It is made of 95% polyester and 5% elasthane(?) I looked up polyester shirts made by Versace - and nothing; posts either said 100% silk or didn't mention material just that it was a Versace shirt. Is it a real Versace or a knock off? (I can sell a real Versace even if polyester) What would I call it - the way the color changes as it moves through or in & out of light? I thought I'd call it a vintage Versace disco shirt? I know it's not a big thing but it is interesting, right? Thank you! Notice how pink/purple front of shirt is in light below & when turned at a different angle to light to photograph sleeve & cuff how dark it gets? It seems it would be a attention getter in a night club with those spinning light from disco balls!
