"Oh, I just threw on anything" may be a tireless, never-ending cliche, but for some this is life. The goal is to make the outfit, not let the outfit make you.
With that said, styling and accessorizing your outfits with all the colors in the rainbow is definitely a fashion don't. I find people asking me how I choose what to wear. I'm not a fashion expert, nor claim to be, but the key to magnifying your fashion physique is simply to experiment, experiment, and experiment more.
Take a few extra minutes to try on various colors and determine if the colors you wear compliment each other or simply clash. Keep in mind, fashion is directly related to what you desire and feel. So be you, be fashionable, be mindful, and be jaunty. This will surely make heads turn when you traverse into a room!
