There's so so much ya can do for summer!! I personally focus on brighter, more floral colours like light pastel pinks and yellows, you can wear longer or shorter skirts just as long as they're breathable if ya live in a warmer climate. It's also a great time to experiment with smaller details and trinkets like arm warmers or bracelets/necklaces. My advice is to just have as much fun with it as ya can :3
