Help dating ethnic (?) knitted sleeveless sweater

[196t's]

Good morning/afternoon/night,

Picked this -- I suppose -- ethnic sweater with 50% off. There are no tags at all. I'm not the wisest with knitted garments, so a little help would be nice. Is it even vintage?
Any help is appreciated.

Great pattern!

I really don't know about the age of this, but I don't think it's ethnic... a little in the style, but in general it looks like a commercially made item.
