Gwen Stefani was just a teenager when she got her start in the band No Doubt, and has been a mainstay in the music industry for more than 25 years at this point. Gwen grew up from a young woman to a superstar mom of three in the public eye, and there’s no doubt (pun intended) that she’s changed quite a bit over the years. The 50-year-old has always been a style icon, but her fashion has definitely emerged with time, as well.
