The Celebrity Big Brother star took to the blue carpet for the Jeans for Genes 2014 party held at nightspot Chinawhite, but unlike most of the guests, Casey didn't rock her denim for the occasion.
Instead, the starlet wore a white two-piece covered in a black shattered print, with the figure-hugging pencil skirt showing off her svelte silhouette and the crop top revealing a flash of her toned midriff.
The model looked very bronzed-up in her monochrome co-ords, which she teamed with nude peep-toe heels and a matching oversized clutch.
And she totally upped the glamour with her hairdo, sporting super-sized brunette locks which tumbled way past her shoulders teamed with bold brows, lashings of mascara and glossy nude lips.
The reality star's night out marked her first official red carpet outing since having her breasts reduced from a GG to a EE cup last month.
Casey first revealed her plans for a boob job in her Daily Star column on 4 August, saying: "I'm 30 this year, gravity will take its toll soon, especially with having boobs from such a young age. I've carried them a long time and I'd quite like to wear backless dresses with no bra for a change."
This year, Jeans for Genes day falls on 19 September with the campaign raising money to help support children affected by genetic disorders. Find out more at jeansforgenesday.org.
