Psychedelic Shirt, Vintage Short Sleeve Summer Shirt, Ymla

Every time, without fail, I wear this shirt I get multiple compliments. It's because it's so unusual. The photos don't do it justice. Warning: Do not take LSD in this shirt and look in a mirror. Asking a lot because I love and don't really want to part with it, but I'm sure you know how that is. The only tag is in the collar and reads: Ymla. Think it's a medium. I think it's polyester but not sure. It hangs nicely. When I bought it the shirt were strangely long so I had it shortened. So now it looks normal except for all the swirling colors in purples blacks, greens, blues...
