The two singers were sighted in the exact same ensemble--a bright red turtleneck and a halved skirt that sports a checkered red design on the lefthand side and a gray or tan-toned pleat on the righthand side. IU wore the two-piece outfit for her album jacket, whereas Seolhyun was seen wearing the sweater and skirt at an 'SK Telecom' event. 

Seolhyun kept it simple with naught but rings on left hand's index finger, adding no loud accessories. She paired the outfit with strappy black pumps which killed two birds with one stone by boosting her height and accentuating her slim legs and ankles. She wore her long wavy hair loose, a wise choice especially with the winter chill right in the air! 

As for IU, it's hard to see the entirety of her outfit, but it's safe to presume that she also wore the pieces in a manner that was similar to Seolhyun's: simple and subdued. It's a shame that we can't see what kind of shoes the singer has on. If there is one notable difference between her and Seolhyun, it's the shimmery red lipstick which matches the red sweater. Seolhyun had opted to brush a magenta hue onto her lips.

This was a bit of a toughie especially since I couldn't see what shoes IU was wearing for her album jacket photo. And also because the whole outfit didn't really flatter either of the singers. The design of the skirt is downright awful--it looks like a tablecloth. But if I had to choose, I would have to go with IU over Seolhyun. IU's slim figure just fits the outfit better and I love her red lipstick! Don't get me wrong, Seolhyun also look good, but the pieces don't really accentuate her voluptuous figure in the best possible way.
