How does one improve their eye for fashion?

Kind of an odd question I guess but yeah basically I’ve been winging it for the majority of my life and I can never really understand fashion. To me the most plain looking things my friend picks up gets a bunch of compliments from strangers and I can’t wrap my head around it. How do I develop my taste is the real question I guess? I dress pretty plain overall probably two-three colors max and it’s always solid colors. Is there even an answer to this? Am I screwed lol? I need personal stylist at this point
