Berets are in again, and more than ever.

The 2016 winter fashion looks are often perfected with a single beret, and celebrities have already joined the trend.

Sulli, former member of f(x), was one of the first celebrities to wear berets even before they were fashionable. She uploaded a photo donning a crimson red beret with a cardigan tied casually on her shoulder.

Even though red berets are hard to style, Sulli flawlessly succeeded as she used the minimum number of colors in her overall look.

The trend continued with another popular girl group member, Seohyun. On her official Instagram, she unveiled a photo showing her elegant and fashionable look.

She pulled off a monochromatic outfit with an ivory beret and a chunky knit sweater in the same color. Just like Sulli in her picture above, Seohyun made the look a bit more posh by tilting her beret to the side.

Last but not least, the latest “beret look” was created by rookie girl group Twice’s Nayeon. She showed up at an event on Wednesday afternoon with a unique style.

She let her long, wavy hair down and put on a navy beret to top it off. The simple cream-colored coat could have made the look dull, but Nayeon kept herself chic with her fancy accessories and a beautiful face.
