After losing a considerable amount of weight, I needed a new bra wardrobe.  I took all the necessary measurements and bought some bras.
Unfortunately, they were "imported" and my 37" measurement did not agree with whoever assigned sizes to these bras.  Although I had ordered 38", I found I needed at least another inch for day-long comfort.  That's where the bra extenders saved my day!  They are wonderful.  Just enough extra length to give a good fit without changing the bra strap alignment  I am very happy with them.
