pathfinder 1e – Is there any way to gain access to Evasion without taking multiple levels of a class?

So, I have a character with a really, really, really bonkers Reflex save. It wasn’t really the design plan, but a combination of class features, ancillary benefits from traits, and stats meant that I ended up with one.

Given that, Evasion would be a really great feature to have – better still, the Twist Away feat, which requires Evasion, would be incredible for this particular character, and thematically fitting.

Problem is, dipping 2 levels of Rogue (or another class) is a larger setback than I’d like.

So, is there any way to get Evasion through a feat or other means? I’m particularly interested in permanent methods, in order to qualify for other feats. One level dips are worth mentioning, but not ideal, and if it helps any, the character is Mythic, on the Trickster path, and can expect to get to Tier 10 ‘someday’ (but not anytime soon).

I’m interested in solutions that might apply for any race/class/level combination, as it seems a handy thing to pick up in a variety of circumstances – especially since Twist Away exists. That said, my particular circumstance is a Half Elf, Swash 1/Investigator 7 (the ACG versions).
