BTS Jungkook JK x Calvin Klein CKJK 3D Long Sleeve Shirt

A Shirt Built Around a Landmark Fashion Collaboration

The base is clean white, styled to let the small navy logo work carry the whole design rather than compete with a busy graphic. This is a CKJK Long Sleeve Shirt, referencing “Jung Kook for Calvin Klein,” the 2026 capsule collection marking BTS member Jungkook’s first fashion design collaboration and the first time in Calvin Klein’s 58-year history that an idol was directly involved in designing the line. The collection reportedly became the brand’s best-performing collaboration ever, selling out across pop-ups and e-commerce channels worldwide within weeks of its May 2026 launch.

Minimal Branding With Maximum Recognition

The front chest carries the “CKJK” wordmark in bold navy block type, prefaced by three small diagonal marks and followed by “EST. 2026” beneath it, keeping the design restrained and logo-driven rather than image-heavy. The left sleeve carries small handwritten-style “CK,” “JK,” and a simple smiley doodle stacked vertically, a nod to the personalized, sketch-like details reportedly worked into the actual collection’s custom hardware and logos. The right sleeve runs “JUNGKOOK” in large vertical block lettering from shoulder to cuff, balancing the understated front graphic with a bolder, more legible sleeve statement.

Fit and Silhouette

The shirt follows a relaxed, slightly oversized long-sleeve crew-neck cut, with a plain ribbed collar and straight sleeves that don’t taper tightly at the wrist. Based on the reference image, the fit sits loose through the body and shoulders, consistent with contemporary streetwear-influenced merch sizing rather than a fitted athletic cut.

Fabric Feel and Everyday Wear

Per Julie Diary’s product specification for this category, the shirt is made from a premium blend of 35% cotton and 65% polyester, giving it a soft, silky, lightweight knit feel that’s moisture-wicking and breathable. It’s built for all-season wear — warm enough for cooler days while still staying cool and dry in summer heat, with ventilation designed to dissipate heat easily.

Styling Suggestions

Worn with straight-leg denim and low-top sneakers, it keeps the look casual and easy to wear daily. Paired instead with cargo pants and a baseball cap, it leans into the same off-duty, motorcycle-inspired aesthetic reportedly behind the original collection’s design direction.

Key Details

This Jungkook Calvin Klein Shirt follows a relaxed, long-sleeve crew-neck silhouette with taped neck and shoulder seams for added durability. The design is applied through dye-sublimation printing, built to resist fading, cracking, peeling, or flaking so the logo work and sleeve lettering stay sharp over time. Per Julie Diary’s product specification, the fabric is a 35% cotton, 65% polyester blend knit, lightweight and moisture-wicking for comfort across seasons. Care instructions call for a cold machine wash, non-chlorine bleach only if needed, hang drying, and a cool iron on the reverse side or dry cleaning; expect a 1–3 cm sizing variance from manual measurement and slight color variation depending on screen display.
