Fergie thinks her style is "all over the map".
The 42-year-old singer - whose real name is Stacy Ann Ferguson - has admitted her fashion choices are constantly changing "like [her] music", but the 'Glamorous' hitmaker has no qualms about experimenting with various wardrobe pieces because she likes to "take risks".
Speaking to PEOPLE about her aesthetic, the vocalist - who has four-year-old son Axl with her former partner Josh Duhamel - said: "It's all over the map just like my music. It's a mood. I like to have fun with fashion and take risks. Sometimes they work, sometimes they don't but I have fun with it and I like to always feel good in what I'm wearing."
But the Black Eyed Peas band member thinks it is most important that an outfit doesn't take over and "wears you".
Speaking about her fashion mantra, she said: "You got to wear the outfit and not let the outfit wear you.
"So if I'm wearing something that is extravagant, I'm owning it."
Fergie has revealed 52-year-old Giovanni Bianco - who has worked with fashion houses including Versace and Miu Miu - for helping her get "back in touch" with her "tomboy" style and her "hard side".
Speaking previously, the 'Fergalicious' star said: "Giovanni really helped me get back in touch with my tomboy side, my hard side, because I had [son] Axl ... had done the music and I was fine in the studio, but he was like, 'You know what, you have this thing inside of you - you have kitten, and that is very natural, but you also have the boyish side.'"
"Because having a son [I was] very motherly, but it was about pulling that tough side of me back out."
