If you want to design a set of clothes that gives people a small fresh feeling, you can consider the following design: For the top, you can choose a loose white T-shirt, made of lightweight cotton or silk material, which is comfortable and breathable. Simple patterns or letters, such as small flowers or simple letters, can be printed on the T-shirt. For the bottom, you can choose a light blue or pink short skirt, with a length slightly above the knee, which looks fresh and cute. For shoes, you can choose a pair of white canvas shoes or flat shoes, which make the whole outfit more natural and comfortable. You can choose some simple accessories, such as a small handbag or a waist belt, to make the whole outfit more delicate.
