The royal's appearance comes as she continues to battle the same illness she faced during her first two pregnancies -- hyperemesis gravidarum, or severe morning sickness. The condition affects about one in every 200 pregnancies and results in severe nausea, dehydration, and low blood pressure, among other things.

She had previously pulled out of the event, but decided to come along at the last minute because she was feeling so well.

Kate donned an Orla Kiely floral frock in a pastel pink hue that was embellished with a contrasting black bow detail waist and three quarter length sleeves. She polished off the chic look with a pair of black block heel pumps and a clutch of the same hue.

The brunette beauty also rocked freshly cut locks, resembling a similar shorter style we saw from the royal at Wimbledon, just weeks before she announced her pregnancy.

The surprise outing comes almost a week after Kate debuted her baby bump to the world during a Kensington Palace reception celebrating mental health workers.

The 35-year-old royal showed off her baby bump in a powder blue lace frock from London brand Temperley that hit just below her knees that she matched with a pair of black pumps and diamond drop earrings worth $3,852 from her go-to designer Kiki McDonough.

Before Kate Middleton was wearing tiaras and fancy pearls, she was the queen of accessorizing. Between the scarf and the French-inspired beret, she looked absolutely flawless in 2007.
