The 26-year-old catwalk queen is seen flaunting her naked figure in a black-and-white commercial for the collection, reported Ace Showbiz.
The nearly two-minute video also captures the ex-girlfriend of Leonardo DiCaprio mowing a lawn, skimming the pool, playing with a baseball bat and smoking a cigar.
The collection offers new range of everyday underwear that is exclusively designed by Refaeli
"My underwear is the clothing article closest to my body, and as such, I want it to complement it and not steal the show. There is nothing better than simple, comfortable, quality clothing," the Israeli model wrote on her website.
"My work means I'm traveling all the time, rushing from city to city and wearing the most incredible, elaborate designs. I love it, but on my downtime I just want to relax and be myself. I don't want my clothes to define me. The collection is about beautifully-made basics that look good and feel amazing. That's all I need," she added.
