Since Plus Size bras start at band size 42, and also have very large cup sizes, there must be something in back to counterbalance a large bust. And that is most frequently a tall powermesh back that is 4" or taller. Provided that the right size band has been selected in the first place, a tall, powermesh back band should smooth out ripples and bumps that have come to be known as the dreaded "back fat." Every woman who wears a fabulous knit dress wants to look sleek and sculptured from the rear view, with the top and bottom edges of the bra band making a smooth transition to skin, so it's totally invisible. Are we dreaming the impossible dream? Absolutely not, and HerRoom is here to help you achieve that smooth, no-lines look under all your fashions.
