For months I had looking forward to a Knix bra. Knix measurements guidelines were followed and finally purchased one and it arrived yesterday. In my mature adult life, this is the ABSOLUTELY WORST design i have EVER had for a bra. I am very small sized, yet the breasts cannot completely fit into the cup. If I force the breasts into the cup and try to adjust the straps, the bra puckers under the arm about 1 inch-1.5 inches and also puckers on the back about 1.5 inches. I am shocked such expensive bras are so poorly designed that it cannot fit even a very small person.
