A relaxed collegiate-inspired long-sleeve shirt built for everyday streetwear.

Attached striped necktie detail adds a preppy collegiate accent without extra effort
Embroidered "UNKONG RETRO" lettering and floral motif on the left chest panel
Woven oval logo badge patch on the breast pocket for a branded finishing touch
Classic point collar and full button placket for a clean, structured front

Fit & Styling
This shirt runs oversized — the chest measures 120 cm at size M, making it ideal for layering over a long-sleeve tee or wearing open as a light outer layer. The dropped shoulder and relaxed body suit those who prefer a boxy, unstructured look. Pair it with slim-fit trousers or straight-leg jeans and chunky sneakers for a complete campus-to-street outfit. The tie detail is pre-attached, so no styling effort is needed. Sizes M through XL are available; refer to the size chart for exact measurements.
Product Details
Fabric: 100% Cotton woven fabric with a smooth, medium-weight hand feel suited to spring and autumn wear. The shirt features long sleeves with single-button cuffs, a chest patch pocket, and a clean plain back panel. A yellow brand label is sewn at the inner collar. The striped tie is fixed to the shirt front. Embroidery and woven patch detailing are applied to the left chest area.

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.
