Fit & Styling
This shirt is cut with an intentionally oversized, boxy silhouette — ideal for wearing untucked over slim or straight-leg trousers, jeans, or joggers. The relaxed shoulder drop and generous chest measurement give it a layered, streetwear-ready feel. It works equally well as a standalone shirt or as a light overshirt layered over a plain tee. The neutral grey plaid palette makes it easy to pair with earth tones, black, navy, or white basics. Refer to the size chart: M fits chest up to 118 cm, with sizing scaling up to XXL at 130 cm chest.
Product Details
Crafted from a lightweight cotton-blend fabric, this shirt is composed of approximately 80% Cotton and 20% Polyester, giving it a soft hand feel with light structure and easy care. Available in Grey Plaid. Sizes M through XXL. Length ranges from 72 cm (M) to 78 cm (XXL). Shoulder width from 53 cm (M) to 56 cm (XXL). Sleeve length from 61 cm (M) to 64 cm (XXL).

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.
