A refined take on the classic knit pullover, this ribbed mock neck sweater features a distinctive vertical row of buttons running along the left chest — a design detail that blends Korean vintage sensibility with a polished, old-money aesthetic. Available in versatile grey and black, it delivers understated sophistication for cooler seasons.
Product Highlights
Vertical side button placket adds a unique, fashion-forward design element
Full ribbed knit construction throughout body and sleeves for texture and structure
Mock turtleneck collar provides warmth without bulk
Relaxed boxy silhouette suits a range of body types
Available in classic grey and black for easy wardrobe integration

Fit & Styling
This sweater is cut with a relaxed, slightly boxy fit that sits comfortably across the shoulders and chest. The mock neck sits close to the throat without being restrictive. It pairs well over a collared shirt or turtleneck for a layered look, or worn alone with tailored trousers or straight-leg jeans. The button detail reads best when left unbuttoned for a casual effect, or buttoned up for a more structured silhouette. Refer to the size chart: M fits chest up to 104 cm, L up to 108 cm, and XL up to 112 cm.
Product Details
This sweater is constructed from a soft mid-weight knit blend, estimated at 80% wool and 20% acrylic, giving it warmth, shape retention, and a smooth ribbed surface. The garment length ranges from 61 cm (M) to 65 cm (XL), with sleeve lengths from 61 to 63 cm. Shoulder widths span 46 to 50 cm across sizes. Hand measurements may vary by up to 2 cm. Available in Grey and Black, in sizes M, L, and XL.

How to Find Your Perfect Size — Every Time
How to Find Your Perfect Size — Every Time
Struggling to pick a size online? Here's a simple trick: instead of guessing, use a piece of clothing you already own — and love the fit of — as your reference point.
Step 1: Pick Your Reference Item Think of a T-shirt you've bought before that fit you perfectly. Find that order and pull up its size chart.
Step 2: Focus on Two Key Measurements For streetwear-style tees, two numbers matter most:
Chest width— too narrow and it'll feel tight
Length— too long and it'll look sloppy
💡 Tip:Size charts sometimes list "Chest" as theflat-lay widthinstead of the full circumference. Here's how to tell the difference:
Large number(e.g., 49in / 124cm+) → likely the actual chest circumference
Small number(e.g., 24in / 62cm) → likely the flat width (garment laid flat and measured edge to edge)
Step 3: Note Your Ideal Numbers Write down the chest and length measurements from your best-fitting shirt. Care about sleeve length or shoulder width too? Note those down as well.
Step 4: Match to Our Size Chart Now check Seakoff's size chart and pick the size whose measurements are closest to your notes. That's it — no more guessing.
Works for Everything This same method applies to hoodies, sweaters, jackets, and more. Do it once, and you'll be able to shop confidently, anywhere — every time.
