As for meat, my advice to you is that young but slightly fleshy boys can choose shirts with bright colors and patterns (such as crimson Scottish plaid) and hide the meat on their bellies. Be careful not to tie the shirts in their pants like middle-aged uncles. Wearing black or other dark pants can "press" the same upper body color. This kind of clothes is suitable for now, spring or autumn. Can be worn with a coat vest.
If it is very hot weather, wearing a T-shirt with a big pattern on the chest can also make others ignore your stomach. You can choose a slightly printed type, the color is brighter, and the T-shirt is "slim". For example, a black T-shirt with color printing.
It should be noted that if you care more about the meat on your stomach, then don't choose low-rise pants. Low-waisted trousers will "evenly concentrate" the fat a few centimeters above and below the waistband to the upper edge of the waistband. Bicycle tires, which were originally only 2 or 3 centimeters long, are likely to become "lifebuoys" of about 5 centimeters if they are pulled by low-waisted pants. Similarly, if you tighten the belt too tightly, it will have this effect. Choosing high-waist pants with appropriate waist circumference can cover your stomach well.
In addition, don't stuff the hem of your clothes into your pants, which will make you look like a middle-aged frustrated Ogilvy Sang, and don't stuff your pants pockets with keys, mobile phones and change ... not only will you look fat, but you will look flustered every time you save money or take your mobile phone, just like a drowning person looking for a lifeline. You can choose to carry a bag. If you don't like it, wear a casual coat with pockets.
