I have a general suggestion, which is intended as a suggestion only.
Get yourself a copy of Vogue or something similar. You're looking for a magazine with ads from Chanel, Bottega Veneta, Ralph Lauren, Guess.
Get yourself a color wheel. Just pull one up on the internet.
Now start looking at ads. Find the colors in the ad on the color wheel. Start with the important colors, the clothes, shoes, jewelry. But got get them all. The model's skin, makeup, eyes, hair. The building behind the model. The sign in the window. The tree down the street. All of it.
Do this for a dozen ads, and you'll know a great deal about styling and managing color to create a high-fashion look.
