A neckline that is extremely low, seemingly supported only by the curve of the breasts or the nipples themselves. Because the clothing appears millimeters away from a nipple or areola slip, this often means there's ample cleavage. This neckline is most common in strapless and off shoulder clothing. Not to be confused with plunging neckline, which is also a low neckline that scoops down between the breasts/pecs.
