These are thicker than the Wacoal No Peeks. They are pretty curvy though. The D/DD doesn't completely cover a DD breast (pregnant) but it follows the contour enough to not look unusual under your garment so in a way it's fine. Could use a larger size. Also, if they were to improve these, it would be great if they had a petal adhered to the inside surface because the nipple does show through without it but less so than the Wacaol No Peek. Would be nice if it had a rigid box to store in the drawer with a polypropylene sheet molded to the same shape to help it keep its shape. Nice that it comes with two pairs.
