I bought exactly the same item number, F2781, in the same size, a year or two ago, and the original ones were perfect (would have given those 5 stars).  However, Calvin Klein has CHANGED the style and fit of this while calling it the same style number F2781.  It used to be a graceful, daintiy demi cup, now it's a dowdy full coverage.  When they changed the look, they should have given it a new style number instead of misleading loyal customers.  See photo of my old one next to the new one in the SAME size-- the center front band became much taller, and the cups cover higher.
