This design features a logo with a white background and a black border. The logo is designed to resemble a baseball, with the words "little sister" and "biggest fan" written in a stylized font that mimics the look of handwriting. The words "little sister" are positioned above the baseball, while "biggest fan" is below it. Inside the baseball, there is a heart symbol, and to the right of the heart, there is a small baseball icon. The overall design is simple and playful, with a clear theme related to baseball and sisterhood.
