Lucy and Ashley made their way to Head to Toe in Carnaby Street to see the designs of Proudlock's Serge DeNimes fashion brand.
Proudlock, who wore his own 'So Serge' top, got rid of his signature tortoiseshell glasses in exchange for black shades! He played host to his guests for the night, which included revealing his collection and presenting live music performances.
We've seen Proudlock show off his T-shirt designs in the E4 reality show, and last month, he also sold his items on a market stall in London alongside former MIC star Caggie Dunlop.
Lucy, who showed off her holiday tan after a sunny break in Turkey last month, channelled the boho chick look, wearing a white off-the-shoulder printed aztec top, jeans and wedges.
Lucy, who split from show villain Spencer Matthews last month after he admitted to cheating on her in Greece, treated herself to a spot of retail therapy before the event. Taking to Twitter, she said: "Bit of retail therapy never hurt anyone #justthebeginning."
Meanwhile Ashley, who recently filmed a role in new British film Taking Stock alongside Kelly Brook, wore dark jeans, a mint green blouse and tan wedges.
Despite Proudlock's close friends Spencer Matthews, Jamie Laing and Francis Boulle not being able to make an appearance, Jamie did send a message of luck.
He tweeted: "Good luck to Ma Boi @oliverproudlock with his @SergeDeNimes POP-UP. The music will be sick #soserge."
