Be professional. This is called a pair of breasts. If you want to reduce this space, you'd better stretch your arms and lift them as long as possible. And underwear is very important. Basically, people with breasts are wearing underwear incorrectly. Squeeze the meat under the back and arms to form a pair of breasts. Change underwear and buy something more expensive, which can squeeze out all the meat on the chest and enlarge the breast. There is basically no way to completely eradicate the accessory breast, which is related to people. Some people who have lost weight will still help their breasts a little, as long as it is not too influential. It's much better to do as I say ~
