Oh Yeon-seo delivered a dreamy, elegant take on the ballet-core trend. She recently posted a series of ballet-inspired looks on Instagram that quickly caught attention. From figure-hugging leotards and floaty skirts to long legwarmers, her styling gives off the impression she could glide onto a stage at any moment.
In one set of photos, she highlighted her feminine side by pairing a floral leotard with a lace-trimmed skirt. A casually tied ponytail and an ivory scrunchie enhanced that classic ballerina vibe, while ivory tights and legwarmers added warmth and a romantic finish.

In another series, she paired a nude-toned sheer top with black shorts for a sleeker, edgier feel. A red bra top layered beneath the translucent piece served as a bold pop of color, elevating the otherwise neutral outfit. Long knee socks and high boots gave the look a contemporary, fashion-forward ballet-core twist.

Her pairing of a black cardigan with a navy leotard also stood out. The lightly draped cropped cardigan contrasted beautifully with the deep navy, striking a balance between classic and modern. Cream legwarmers softened the overall look, and her relaxed pose—lying on the floor while gazing into the camera—felt effortlessly alluring.

The soft blue cross-wrap cardigan with black shorts was another standout. Reminiscent of dancers’ practice wear, the lightweight knit looked casually chic layered over a tight leotard, creating a well-balanced silhouette. Cream legwarmers that reached the ankle added cozy warmth.
The most romantic ensemble arrived in pastel pink. She styled a loose pink sweater with ivory shorts and even matched her ballet flats to maintain a cohesive palette. Delicate hues and soft shapes captured the essence of ballet-core, and even in relaxed poses she carried an understated elegance.

Oh frequently experiments with diverse looks and consistently shows a keen fashion sense. This ballet-core series suits her soft, graceful image and has resonated with many fans. The combinations feel both practical and polished—easy to adapt for everyday wear—and are poised to become a spring trend.
