This black and white striped sweater delivers a bold, preppy aesthetic through wide horizontal stripes and a classic polo collar. Crafted in a chunky open-knit construction, it features a three-button placket at the chest and an embroidered heraldic crest badge on the left chest — details that elevate it beyond a standard striped pullover. Designed for both men and women, it sits at the intersection of Korean lazy-style dressing and heritage rugby knitwear.
Product Highlights
Wide black and ivory horizontal stripe pattern with strong visual contrast
Polo-style collar in solid black with a three-button placket
Embroidered shield crest badge on the left chest for a collegiate accent
Chunky open-knit fabric with ribbed cuffs and hem for structure
Relaxed, slightly oversized silhouette suitable for unisex styling
Available in sizes M through XXL with detailed measurements provided
Fit & Styling
The sweater runs with a relaxed, boxy fit — the chest measurement ranges from 106 cm at size M to 118 cm at XXL, making it comfortable to layer over a fitted turtleneck or wear alone over wide-leg trousers or straight-cut jeans. The polo collar adds a smart-casual edge that works equally well tucked into high-waisted pants or left untucked for a streetwear-leaning look. The ivory and black palette keeps styling versatile across seasons.

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.
