IVE's Rei revealed the behind-the-scenes of her styling for the new song "XOXZ." Starship Entertainment posted a new episode of the YouTube channel "Try It Out Rei," featuring Rei, on the 2nd. Rei began introducing the "XOXZ" stage styling, saying, "I thought many people were curious about my outfit and styling, so I turned on the camera like this."

On the first comeback stage, Rei showcased the short hairstyle from the music video. About her first attempt at a short hairstyle, she said, "It's a wig, but I think it suits me better than I expected. I want to cut my hair short someday." She attracted fans' attention by explaining the hairstyles she wants to try in the future.

On the second day, Rei introduced makeup focusing on eyelashes and highlighter. She said, "I thought I had to show something today, so I brought glasses," and took out the glasses gifted by Dive (official fan club name). She completed the styling by choosing a fringe piece that matched well with the glasses, took commemorative photos, and expressed satisfaction.

On another stage, Rei introduced styling with her favorite wing point, calling it "Rei Core" day. She said, "I saw on SNS that attaching glitter freckles is trending overseas these days, so I suggested it to the makeup artist," showing her trendsetter sense and passion.

She continued, "The charm I pursue will change every day during this promotion. I'm thinking about various looks because I want to show different sides of myself." On the last day of the first week of the comeback, she appeared in styling reminiscent of Snow White. Rei said, "The clothes I'm wearing now were worn multiple times across concept photos, music videos, and video content, so I thought a lot about how to give a new feeling."

She captivated fans' tastes by showcasing various styles, from chic short hair to gyaru style and cute "Rei Core." At the end of the video, Rei said, "I wanted to share detailed information that hasn't been revealed in IVE content, so I shared it. I hope you like it a lot," ending warmly.

Rei offers unique entertainment every Thursday at 7 p.m. on the YouTube channel "Try It Out Rei."
