The Celebrity Juice star, 33, wore a yellow frock to WilliamVintage's summer party held at the famous Mayfair hotel, Claridges.
The former Radio 1 DJ looked gorgeous in the loose-fitting dress which hid her baby bump, but flashed her toned pins.
Before arriving at the event, Fearne gave her one million followers a sneak peek at her accessories...
Sharing a picture of her vintage white box handbag with daffodils and her animal print heels, Fearne simply said: "Tonight's bag and shoes."
After attending the do, Fearne said: "A lovely evening at @williamvintage summer party with @sineadmckeefry."
Actress Helena Bonham Carter, presenter Laura Whitmore, former Made In Chelsea's Millie Macintosh and chef Gizzi Erskine were also at the glitzy do.
Fearne's super-chic look was a far cry from one she shared with her Instagram followers just days before.
After the Glamour Women of the Year Awards, where she was awarded Radio Personality of the Year, Fearne woke up the next day with some serious bed hair!
She told us: "Have not brushed my hair since the Glamours last night. Regrettable."
Fearne is pregnant with her second child. She already has a two-year-old son called Rex with husband Jesse Wood, son of Rolling Stones rocker Ronnie.
