The girlboss era might be ending, but the power suit isn't going anywhere. We saw tailored suits pop up during designers' fall collections earlier this year, and now it's time for them to make their big autumnal debut. Recently, celebrities like Charli XCX, Demi Moore, Nicole Kidman, Miley Cyrus, and Cynthia Erivo have been seen rocking a tailored suit look on the red carpet. While oversized blazers and pant suits are easier to style, this tailored fit can feel tricky when you're not working in corporate. The level of "seriousness" depends on how tailored the fit truly is—keep it looser for a more casual outing or slimming for an elegant night out.
