Jen wears a brown dress for the first part and there's quite a few nice glimpses of the bare tops of her breasts down the front, which gaps open as she leans forward a few times. The material appears too coarse for any clear nippleage, though, just a hint.
She then wears a dark dress for the second part, and there's a hint of nipple in a brief shot, but the dark colour makes it a bit unclear.
