ITZY's Yuna, Fall Begins in the Fitting Room: Five Moments from 30 Seconds of Dynafit

This fall, Dynafit's 30-second "Fitting Room" commercial featuring ITZY's Yuna is a short yet captivating highlight reel. Set in the intimate confines of a fitting room, it captures Yuna's sense of rhythm and playfulness, as well as her intense focus as a performer, in every single shot.

Yuna's fitting room is essentially a "30 seconds behind the scenes." The nerves and excitement before the performance, the intense concentration just before the cameras roll, and the subtle playfulness in front of the mirror—all of this seamlessly flows together in a single shot. Viewers loved two key moments:

First, the scene where Yuna puts on a new look, moves to the rhythm in front of the mirror, and subtly changes her expression.

Second, the speed of the "look transition" as the fitting room curtains flutter open. Yuna demonstrates through her facial expressions, gaze, and steps that "a change in outfit changes the energy."

Episode 1

"A 0.5-Second Smile in Front of the Mirror" The shortest yet most impactful part is the length of the smile. Yuna doesn't fully smile. It's that 0.5-second smile that rises slightly and then disappears. This brief smile conveys the character of the new product: sporty yet delicate, cool yet warm. This subtle shift in expression leads viewers to imagine, "Would I feel that way if I tried it on?"

Episode 2

"The Curtain Transition Drop" The timing of the music drop and the swipe of the curtain are the core "pleasure" of the video. The curtain serves as a fitting room prop, a scene transition device, and an instrument that visualizes rhythm. With the drop, the silhouette changes, the color palette shifts, and Yuna's steps feel a half beat deeper. This is a moment that likely prompted comments like, "Even the sound of the curtain sounds like a beat."

Episode 3

"Shoelace Fingertips" A brief, detailed shot of someone adjusting their shoelaces captures the essence of the scene. The angle of their fingertips and the rhythm of their head bowing subtly align with the music. This moment marks the intersection of functionality and style. The brand message, "Designed for the Active," resonates with the skin faster than words can convey.

Episode 4

"Headphones Off" The act of removing headphones is a silent signal that "ready to go." It's a shift in confidence before stepping onto the stage, a completion of the routine. This small gesture transforms the fitting room from a "waiting room" to a "runway line." The viewer senses this momentary shift in atmosphere and naturally becomes immersed in the experience.

Episode 5

"Steps Beginning from the Toes" The camera begins with the toes, gradually moving up the frame to the upper body, emphasizing Yuna's dance moves and the "movement" of her outfit. The flow of her running pants and the wind-like texture of her windbreaker come to life alongside her steps. This is the synergy created by the combination of a model with exceptional dance moves and sportswear.

The style tone is sophisticated, modern athleisure, perfect for fall.

A pop of color shines on a neutral base, and the layering is light yet structured. The shoulder and waistline are particularly defined, maintaining mobility while creating a slim silhouette. The soft, diffused lighting of the fitting room accentuates the texture of the fabric, and the angle creates a seamless connection from shoulder to fingertips.

What's interesting here is the mastery of this "advertisement that doesn't feel like an ad."

Rhythm and gestures, rather than explanations, convey functionality. Viewers see "the moment of improvement" rather than "why it's good." The short 30-second runtime features evenly spaced "checkpoints" to prevent viewer fatigue. The initial 3-second engagement, 10-second look transition, 20-second detail, and 27-second finale are all part of the composition, exquisitely blending TikTok/Reels grammar with the polish of a TVC.

The brand message is concise.

Even before leaving the fitting room, Yuna has already created a "stage of movement." Therefore, Dynafit's fall collection isn't about "clothes that only prove their functionality once you step outside," but rather "clothes that initiate movement the moment you put them on." This is how it proclaims the "absence of boundaries between everyday life and performance."

From a marketer's perspective, this ad shares three key points.

First, the rhythmic transitions are easily meme-able. Short movements like swiping curtains, turning off headphones, and fingertips of shoelaces can be completed in a 3-5 second clip.

Second, comparing facial expressions before and after changing looks sparks a fan community's "capture game."

Third, the fitting room is a space where everyone feels a sense of experiential intimacy, making it ideal for expanding into a "challenge to copy in your own room."

Ultimately, these 30 seconds suggest the experience of wearing "the movement called Yuna."

 Functionality is conveyed through movement, style through expression, and the brand through rhythm. This makes it hard to put down. As the curtains flutter open once more, we anticipate another look. This fall, Dynafit's fitting room was the smallest stage, yet the most compelling showcase.
