First of all, a simple pure white T with jeans or sweatpants. In fact, it is unnecessary to wear colorful clothes to attract people in summer. Sometimes, as long as you have a good temperament, simple white short sleeves can wear the feeling of a sunny boy. I prefer this comfortable dress.
The second one is a jersey. In fact, most girls really have no resistance to boys wearing jerseys. Boys who often wear jerseys will automatically exude a charm called "youthful vitality". In summer, basketball courts and campuses often meet a group of boys wearing simple jerseys. It's really a "warm heart" feeling.
Third, if you think you have a good figure and don't have much meat on your upper body, you can consider buying more shirts. Boys wear shirts and can wear them well, which is very extra points. Shirts are very temperament items, and they are very good at modifying the figure. Even simple solid color shirts will make boys very individual.
In fact, not only clothes, but also shoes are very important in my eyes. Boys should wear better shoes. You don't have many pairs of famous brands, but at least you should have a few pairs of suitable and satisfactory sneakers. Shoes are a facade for most boys, and the wearing of shoes is also the finishing touch of the whole dress.
Not only the style of dress, hairstyle and personal temperament, but also some hats and necklace accessories are very important. Try different styles slowly and find the one that suits you is the way for everyone.
