The so-called adjustable underwear can help shape the body and breast enlargement. As long as it is aimed at obese people, the principle is to realize that fat can be moved and has memory, and obese people can put body fat into a cup when wearing it. Only by correctly wearing adjustable underwear can we achieve the effect of body shaping and breast enhancement. I used to sell adjustable underwear, but if you are thin, there is no need to pass it on, because it doesn't have much effect. When wearing ordinary underwear, you can bend over 45 before wearing it, so it looks fuller.
