Kate Middleton has made only a handful of public appearances since the announcement of her second pregnancy, but boy, is she making up for lost time.

Although the expecting mom has reportedly been recovering from acute bouts with morning sickness, Middleton absolutely glowed in a knit black Temperley London dress showcasing see-through cut-outs along the arms, neck, chest and skirt.  But make no mistake — Middleton looked anything but inappropriate. Kate's frock, which retails for around $960, featured a nude slip that kept her classy, contemporary and sexy.
