It's ehh, okay. Mixed impression.
Sounds just like
Perry, which is kind of preppy surname, so there's that vibe about it - seems similar to
Teri or
Jeri in the 1960s.
I like
Teri, though, and I think in real life if I met a
Peri I would think it was nice. NMS exactly, but nice.
Considering whether I'd personally favorite it as a name, though ... mostly it reminds me a lot of "peri bottle" (perineal wash bottle or bidet bottle, used postpartum) - that ruins it for me, tbh. And there's the Doctor Who thing, which makes it seem a tad geeky. I don't like the "fairy" meaning.
