The new mum showed off her pins in the frock, which rested just above her knee and looked as glam as ever, with her blonde locks styled into boho waves.
Her dress proved to be a great little number to flatter her body shape overall too, as the slimming black colour was offset with a bold pattern, which drew attention to the centre of Fergie's outfit and made her silhouette appear smaller.
She then accessorised with a pair of red heels, a black clutch and some cat-eye sunglasses that featured bright yellow lenses.
Fergie, 38, was no doubt excited to be celebrating her sister Dana's baby shower, as it wasn't long ago that she welcomed her own tiny tot, Axl, into the world with husband Josh Duhamel.
We can imagine she and Dana will be swapping lots of parenting advice and getting their children together for play dates in the future!
Axl Jack Duhamel was born on 29 August and Fergie and Josh have been infatuated with him ever since he arrived.
Although the couple have been spending a lot of quality time with their new son lately, they have each made sure to enjoy the night away from home too.
Last month, Fergie took a break from tending to her little one to hang out with Khloe and Kim Kardashian at a Kanye West concert.
