That kind of clothes is not good for your health ... don't do that, it will be exposed sooner or later. And everyone's impression of you is fixed, and it won't change much if it looks smaller.
I suggest you adjust your diet and do aerobic exercise every day. I believe you will lose weight soon.
Don't diet! Don't diet! Don't diet!
Don't buy any boastful diet pills! Will rebound!
