If your upper body is fat, then you should never choose short-sleeved or tight-sleeved clothes, because they will expose all the meat on your arms, which is particularly ugly and strange. This will not only improve your figure, but also make you look very bloated, and even make people ignore the particularly slender side of your lower body.
In summer, girls with fat upper body and thin lower body can buy some dresses with sleeves, which can help you stop the meat and show your lower body. It is best to choose some straight dresses at the waist, so as not to show your not-so-thin waist. Or choose some clothes with a sense of design, such as bubble sleeves or bat sleeves. They have a sense of design and fashion, which can not only help you cover up some defects in your figure, but also make you look fashionable and thoughtful, which is very suitable for your figure and not suitable for girls.
In winter, I think it is very advantageous for girls with fat upper body. You can choose some wide cotton-padded jackets to cover the flesh of your upper body, and then wear a beige tights with a pair of knee-high boots. This can show the lines of your legs well, and also cover all the flesh of your upper body, which is especially thoughtful. Many girls with fat upper body around me especially like winter, because in winter, they don't need to hide their flesh.
