This Korean-inspired campus sweater set combines a ribbed V-neck knit vest with a blue striped button-up shirt underneath, creating a polished faux-layered look in one piece. A woven shield badge embroidered with "IDVENSKY" sits on the left chest, and a removable striped tie completes the preppy school aesthetic. Available in cream and wine red, it suits both casual and smart-casual occasions.
Product Highlights
Faux two-piece design: knit vest bonded with a long-sleeve striped shirt for an effortless layered look
Embroidered shield badge patch on the left chest with "IDVENSKY" lettering
Removable striped tie included for a classic school-uniform finish
V-neck ribbed knit vest with ribbed hem and armhole trim for structure and stretch
Available in cream (apricot) and wine red over a light blue striped shirt base
Relaxed unisex silhouette suitable for a range of body types
Fit & Styling
The silhouette is relaxed and slightly oversized, making it easy to layer over a tee or wear as shown. The faux-layered construction means no tucking or adjusting is needed — the shirt collar and cuffs are built in. Pair with straight-leg trousers, pleated skirts, or wide-leg jeans to lean into the retro campus aesthetic. The tie can be worn or removed depending on how dressed-up you want the look. Refer to the size chart: S fits a 56 cm half-chest, M fits 58 cm, L fits 60 cm, and XL fits 62 cm.
Product Details
The knit vest portion is constructed from an acrylic-blend yarn — estimated at 80% acrylic, 20% wool — providing warmth and shape retention with easy care. The shirt underlayer is a cotton-polyester blend woven fabric with a fine vertical stripe. The badge is sewn-on woven embroidery. The striped tie is included as an accessory. All measurements are hand-measured with a 1–3 cm tolerance.

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.
