Technically this fit. But not well. The cups were not designed to really hold a natural D cup. i also found the sides rolled up quickly leaving an unsightly bulge. Certainly did not deliver on the T-Shirt promise.
Most T-shirt bras still have a noticeable edge if you're big breasted (34F). This one blended in nicely with the rest of my body. The cups are also rather rigid in construction. I feel like my smaller boob is floating around inside it a little so I would like to try a smaller size to see how that fits, but I will definitely be glad to own one of these bras when the dust settles.
