There is little point in creating a style for an imaginary persona, climate, environment, or lifestyle. Identify your needs accurately and honestly. Build an effective wardrobe that satisfies those needs. One that you can easily maintain.
What’s practical and easy for one person might not work for another. Pinpoint your personal, practical priorities. Make sure that your clothing, footwear and accessories are comfortable, attractive to you, and don’t fight with your day.
Sometimes practicality is a trade-off with fashion or aesthetics, but you don’t need to be purely practical all the time. Find the balance that works for you. The most stylish outfits are the ones that serve your needs, whatever those happen to be.
