Hello Again Y’all! This seems to be homemade(no labels) but decently sewn....also seems to work with the zipper in front or rear. Wondering is this is 60’s or 70’s? My wife is guessing back half of the 60’s FWIW. Thank You!
This might be traditional wear, rather than hippy. Those long side slits, on both sides, I associate with something that's meant to be worn over trousers. Might even be menswear? I'm not sure about those sleeves though, they seem unusual. Tagging @Joyatri as she knows this stuff better than me.
I don't think this is home sewn with the overlock seamed stitching, did you check the side seams for a label? Agreeing with 70s.
The fabric looks like terry cloth (toweling), is it? I would say post-swim or bath robe. Although it wouldn't necessarily be menswear, the colors have a masculine vibe, however the sleeves look more like women's. I would say late 60s to early 70s myself.
Not really terry cloth...more like a heavier/slightly softer version of the material used for those cheapish souvenir hoodie/ponchos you find in Mexico/Central America. I suppose it’s similar to terry cloth but with a very “low pile.”
