The secret to fashion is understanding that all trends will die at some point, and even though most come back around later, you can get more wear out of your clothes when you have basics that can go with multiple outfits.
Think about it: Why do you think Kim Kardashian ALWAYS looks polished, even when people think her outfit is basic? She knows the secrets.
Go for nudes, neutrals, and basics like tank tops, midi skirts, jeans, blazers, and one-toned shirts. Then, you can go out and buy a few trendy articles of clothing for your closet, like a sequined blazer, or ruffled-tops, or maybe some statement-making shoes.
