Bests & Worsts Reviews from Amazon

I purchased this item after spending too long reviewing product ratings and reading other customer reviews. I felt compelled to write this, as I had not seen anyone review for this defect. After losing 40lbs, I was so excited to purchase a bra in a standard size. I was so disappointed that this bra band does not even come close to measuring true to size. I ordered a 38D. My band measurement is 40. It's a stretchy material so I expect that it will fit. The bra measures (non-stretched) at 28 inches. Sure it will stretch to 38 inches, but is that really how it's supposed to be designed and worn? Wear it either super tight or with 10 inches of bra extender?! I hate this about women's clothing in general; that the size/measurement doesn't correspond to the actual size. Is this a manufacturing defect or just the purposeful shorting of material on a product?
