How does summer fashion differ on the west coast vs. east coast?

I'm a New Yorker traveling to the West Coast for the first time! I will be spending a few weeks in LA in July for work (also gonna be a bit of a vacation). I know the fashion is different over there but I'm not quite sure in what way. My personal style is pretty alternative and can lean a bit boho in the summer, which I think might be fitting over there?
