The model and MTV's Ex on the Beach star didn't leave much to the imagination in her crisp white frock with a plunging neckline as she arrived at Kensington Roof Gardens in London on Thursday (9 April).
Are you not a bit cold Chloe?!
She finished her look with sky high heels and a gold necklace from her own So In Fashion line, which you can pick up for £14 here.
The star launched her own clothing collection last month, priced from £10 to £70.
Chloe was just one of many stars who attended the annual cancer awareness fundraising bash. Others there this year included TOWIE's Lydia Bright, Ferne McCann and Arg, Mark Wright, Jake Quickenden, Sam Bailey and Sinitta.
