Okay yeah, the shadows under her cleavage in the one with the black top looks weirdly artificial, and the one with the pink stripes is very clearly edited or touched up. Beyond that though they look real, you can see the pores on her skin just beyond the edge of the cloth in a few and it looks real, so either she is stacked or at least got implants, but given the shape and sag I have a hard time thinking the shape isn't natural, which is why it looks weird in the pics from the second post because her bra is doing crazy heavy lifting.
