Carla, I was being a little flip when I said you could use the whole color wheel with a 2-color print, but you showed it's true. Wow! Using your example of a blue & green piece, blue and green match, yellow is adjacent to green, orange is complementary to blue, red is complementary to green, purple is adjacent to blue, and we're back where we started.
Sal, is that white in the boho blouse? If it's beige, you could wear it with khaki. Either way, I bet it'd work with red. But maybe that's just because I like red--I think it'd work with all those things you posted. You mention wearing lots of things with jeans. For the longest time, that was a trap I fell into. I'd buy tops thinking that it was ok not to have something to wear them with in mind, because I could always wear them with jeans. Probably would've been OK, except I hardly wear jeans! They weren't quite orphans, but daddy almost never came to visit.
