If you want to make your chest shape better, more compact and concentrated, and not sag, remember to wear a small vest. After each dressing, you must put your hand into your small back and move a pair of breasts in the direction of inward concentration and upward support, so that at least the small vest can use its unique tightness to prevent your breasts from expanding or sagging. Also achieved the effect of shaping!
You can find your own vest to wear first. If your mother sees it and asks why you are wearing it, you can say to her, "I still think it's more customary to wear a vest, which can keep you warm in winter." !
