f(x)'s Luna is now following the trend of affordable red carpet dresses started by IU and Kang Sora. On January 7, the idol attended a launching event for cosmetics brand Benefit at the Yeoksam-dong's Alver Café. She walked the red carpet to show her support for the new Roller Lash mascara, which will become available to the public on February 27.

Luna made her appearance while wearing a strapless, pink Style Nada dress worth $49. The dress is called the 10th Anniversary Tube Top Dress and a portion of the sales revenue is donated to charity. The dress is distinct because it has a quirky assortment of caricatures which include a cactus, cake, dollar sign, cross, and other disconnected designs.

According to Style Nada, "Donning this dress is the perfect way to reveal your beautiful shoulder blades while looking hip and funky. Done up with tube top, back zippers, and a high waist skirt with a short, flirty A-line silhouette, this tube dress is flashy and will get you noticed in a good way. Dress it up with heels and a jacket or layer it over a top for a quirky look."

Luna finished off her look by accessorizing with a tiny, circular tote and black, chunky pumps.

You can shop for the dress and see it in more detail below.

K-pop idols continue to prove that style is all about confidence not price. IU wore a $25 dress to the 2014 Melon Music Awards, then Kang Sora wore a $30 dress to the 2014 Mnet Asian Music Awards, and now Luna wore a $49 dress. Who will be next?
