The 33-year-old actress says she likes working with the brand because they are not as rigid as other label, reported Contactmusic.
"Sometimes when you work with big brands, you feel they have a very specific formula and I think Ann Taylor goes further with it. Ann Taylor isn't afraid of a little sexiness. I think it's about a working woman who can own her own sensuality," Hudson said.
The actress also said that she is looking forward to starring in a fall campaign because it means she can layer up.
"Fall is always my favourite season. I love layers and Ann Taylor is really going for more colour and prints and fashion and stepping out of the box for their company," she added.
