The 30-year-old businesswoman is set to release '365 Style' later this year and she insists her new guide to choosing outfits will work for every one on any budget.
Speaking to Celebuzz, she said: "The 365 method I found works for any woman with any budget. So what it is is you take the three most common occasions that you dress for, so let's say for a college girl it would be school, after school and weekends going out and then you do the six stands for clothing staples, and the five is for the accessories.
"If you mix and match and interchange for each season I guarantee you will find getting dressed much easier."
Nicky and her sister Paris, 33, have been well-known figures in the fashion industry over the years and the blonde beauty admits the '365 Style' has been an project she wanted to follow through for some time.
She explained: "It started when the whole social media boom happened with Facebook and Twitter and MySpace and all that, people started writing me asking me what to wear.
"Of all ages, I would have young girls writing in 'I'm going on a date and am wearing a red dress, should I wear silver shoes or gold shoes?' ... Men, women, and people were asking and I love fashion. It was a really fun subject to write about, I must say."
'365 Style' is set for release in September.
