Nickel! Having a large chest when I gain weight bras shake me and it's difficult to find cheap bras that cut properly. And it's a great idea to not having to buy lingerie for each weight. They adapt perfectly to bras that I already and as there has all the colors it's just perfect! Only problem is when you have 3 hooks but still want it. I recommend to those who can not or do not want to buy bras every weight gain!
