Solid colorway available in Black, Charcoal Grey, and White
Relaxed straight-cut silhouette with a slightly dropped hem

Fit & Styling
The shirt is cut with a relaxed, slightly oversized silhouette — roomy through the chest and body without being boxy. It sits at the hip, making it easy to wear untucked. Pair it with slim chinos or straight-leg trousers for a smart-casual look, or wear it as a base layer under an open overshirt or bomber jacket. The mandarin collar keeps the neckline elevated without requiring a tie.

Product Details
Material: 95% Cotton, 5% Elastane. The fabric has a smooth, medium-weight hand feel with a subtle structure that holds its shape through repeated wear. Available in sizes M–XXL. Machine wash cold; lay flat to dry recommended to preserve shape and color.

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.
