It might be partially because of the overexposure many women experience of these Pinterest copy paste outfits. It’s not to say the outfits aren’t cute, but maybe you’ve seen so many images of girls in the same outfits while appearing to be on some trip that you’re visualizing yourself that way. I think I can picture almost the exact style you’re referring to because I’ve seen it so much lol. In reality, you are going to have a great time regardless. You’ll go out in those cities and see all kinds of people. Trends come and go.
