I tried both 40C & 40D in this ridiculously uncomfortable bra. The band and straps were too tight, the cups were way too small, and as far as being "lightly lined to prevent show-through," these were full-on padded cups, easily a half-inch thick, that could stand up vertically by themselves when placed on the bed! I felt like I was wearing Roman chest-plate armor held on vicariously by skinny, spandex bands. The padding was so bad, it actually ADDED weight to my chest! Women 40 size bands and up with cups larger than a B, would be wise to move on.
