Trends ebb and flow on the runways every season, but looking at the bigger picture, 2019 was the year of unexpected trends. And you can thank celebrities for that: Stylish stars hit the streets in daring pieces that were all about embracing the surprise factor. These trendsetters didn’t just carry any ol’ bags around—their bags had to be either super tiny, or super huge. Think they wore simple, sexy strappy sandals to go with them? Think again. Kim Kardashian West revived the ’90s flip-flop heel instead, which went on to become the most polarizing footwear style of the year, embraced by everyone from Rihanna to Katie Holmes.
The main 2019 trend takeaway? This past year was all about stars finding the most unlikeliest—and flashiest—pieces from forgotten decades, and then making them (somehow) chic again. Below, the six unexpected trends that took over 2019.
1. Sexy Cardis & Sweater Vests
A look that was first ignited in the early fall (which is prime knitwear season, after all), stars put a sexier spin on both cardigans and sweater vests this year. Who could forget Katie Holmes’s Khaite cashmere bra and cardigan set that went unexpectedly viral? Everyone had to have it! Model Bella Hadid also did a cooler spin on the sweater vest when she wore a knitted utility vest, by emerging designer Reese Cooper. More recently, Harry Styles took his impressive knit game to the next level, wearing a sweater vest covered in sheep.
