Personally, I suggest you do more exercise! I used to be a fat man, but people who lose weight through exercise have a lot of chest fat, so they become droopy. This may be what you call "sharp"! Let me talk about my previous weight and height ~ 14 years old ~ 126 kg 150 cm tall! My first impression when people see me is that I am fat. Now when people see me for the first time, their eyes always show interest. /kloc-started doing push-ups at the age of 0/4. I can only do it for 8 ~ 20 ~ at first, then 40 ~50 ~ 100 ~ at most, I did it for 250 times for half an hour. This exercise is very exciting for my chest! I'm not afraid to make you laugh when I say it! When I rose to 1, my chest was very developed! Some girls with small breasts in my class are not as big as me! I'll give you two suggestions ~ the first is fitness, and the second is to wear some loose clothes as much as possible, so that the "sharp" phenomenon will not be too obvious!
