I have compiled a collection of looks from the Instagram of Lee Si-an, who made her face known through Netflix’s ‘Single Hell 4’ in 2025 and is making her debut in a travel variety show this year with ENA’s ‘Zimzalabium,’ featuring everything from a gray cropped tracksuit look to a yellow cardigan look, a check shirt layered look, an all-black knit look, a camel belted coat look, a navy jacket scarf look, and a brown suede jacket look.

As I flipped through the photos, I thought that the sense of style stood out, ranging from comfortable tracksuits to neat jackets, where a single color was picked out to add a pop of color to basic clothes.

▶ Key Summary

Lee Si-an reveals her recent looks, ranging from a gray cropped tracksuit to a yellow cardigan, a layered check shirt, a camel coat, a navy jacket, and a brown suede jacket.

- A former trainee who appeared on 'Idol School' in 2017 and 'Produce 48' in 2018, appeared on Netflix's 'Solo Hell 4' in 2025.

She appeared on ENA's 'Zimsalavium,' which first aired in August, and is also reportedly active as an official friend for the Spanish brand Bimba y Lola.

The first thing that stands out is a photo taken by the riverside where the sunset light spreads over the waves.

It was a training look where I layered a gray crop t-shirt over a pink tank top and matched it with jogger pants of the same color.

I spent the longest time looking at the pink tank top peeking out slightly over the crop top in this outfit; it added a subtle vibrancy to the calm gray set-up, completing a comfortable yet lovely atmosphere.

With wired earphone cords hanging down, holding a tumbler and wearing a black jacket, the sight of him running his hand through his hair looked like a walk along the river after a workout.

It is difficult to confirm the exact brand of the training setup.

The following is a photo taken on a stone wall path draped with green vines.

It was a look featuring a vivid yellow round-neck knit cardigan.

I spent the longest time looking at the single round button in this outfit that matched the color of the cardigan; it added a cute detail to the vivid yellow knit, completing a fresh yet lovely atmosphere.

With the silver rings layered on the finger holding the cell phone and the black bag slung over the shoulder, it was a scene like a spring afternoon stroll.

It is difficult to confirm the exact brand of the cardigan.

This time, it's a high-angle selfie taken in an alley where a van is parked.

It was a look where a yellow knit camisole was layered over an oversized check shirt.

I spent the longest time looking at the single pair of black glasses hanging on the front of the camisole in this outfit. They added a witty touch to the preppy layered look, completing a casual yet intellectual vibe.

The sight of you wearing gray socks and brown loafers with a black Boston bag felt cheerful, like going to school.

It is difficult to confirm the exact brand of the shirt and bag.

The following is a photo taken on a lawn full of cherry blossoms.

It was an all-black look with a black short-sleeved knit and black pants.

I spent the longest time looking at the white leather shoulder bag worn over my shoulder in this outfit. It created a vivid contrast to the all-black look, completing a chic yet bright atmosphere.

The sight of someone walking with an ice drink and an ivory jacket in one hand looked like a scene from a cherry blossom outing.

It is difficult to confirm the exact brands of the knitwear and bag.

This time, it's a photo taken from a cafe terrace with a red brick building in the background.

It was a look featuring a camel wool half coat with a belt tied around the waist, paired with black stockings.

I spent the longest time looking at the coat belt that cinched the waist in this outfit, as it tidied up the voluminous silhouette of the coat, completing an elegant yet feminine look.

The sight of him tilting his head slightly and smiling next to the green latte on the table was the very essence of a leisurely winter afternoon.

It is difficult to confirm the exact brand of the coat.

The following are photos taken on the terrace in front of the gray wall with shutters.

It was a look consisting of a navy jacket with gold buttons, a white inner top, and white wide-leg pants.

I spent the longest time looking at the silk scarf lightly draped around the neck in this outfit. It served as a classic accent to the navy and white combination, completing a neat yet sophisticated look.

From the shot of sitting at a table holding a coffee to the shot of standing in front of an arched window taking a sip, scenes reminiscent of a French-style weekend unfolded.

It is difficult to confirm the exact brand of the jacket and scarf.

The last one is a photo taken on a wooden bench next to the stairs.

It was a look consisting of a brown suede jacket worn over a gray T-shirt and paired with white shorts.

I spent the longest time looking at the green baseball cap placed on the chair in this outfit. It served as a refreshing color accent to the brown-toned look, completing a vintage yet cheerful atmosphere.

The side profile of you looking into the distance with a black quilted chain bag by your side looked like a scene from a photoshoot.

It is difficult to confirm the exact brand of the jacket and bag.
