The 32-year-old, who is in a relationship with former rugby star Thom Evans, always chooses outfits that flatter her curvy figure and accentuate her waist in order to look her best, reported Contactmusic.
"As a curvy girl, I have to show off my waist and legs otherwise I'd look like a balloon. The 50s fit and flare frocks are so flattering and you can add a belt to nip in your waist," Brook said.
The brunette beauty also said that red lipstick and her favourite fragrance are all she needs to get ready in a hurry.
"Curl my eyelashes, slap on red lipstick and spray on my favourite perfume, Fracas by Robert Piguet," she added.
