This oversized button-up plaid shirt brings high-street American style to everyday wear. Available in a rich brown multi-check and a bold red tartan, each colorway features a classic point collar, dual chest pockets with button flaps, and a full button-front placket. The standout detail is the large embroidered lettering running down the left sleeve alongside a monogram logo at the hem — giving this flannel-style shirt a streetwear edge that sets it apart from standard checks.

Classic plaid / tartan woven pattern in two colorways: brown multi-check and red tartan
Large sleeve embroidery and monogram logo at the lower front hem
Dual chest pockets with button-flap closures
Full button-front placket with point collar
Relaxed oversized silhouette — suitable for unisex / couples styling

Fit & Styling
The shirt is cut in a relaxed, boxy oversized fit that works well worn open as a lightweight layer over a tee, or buttoned up as a standalone top. The dropped shoulders and generous chest measurement make it a comfortable unisex piece. Pair with straight-leg jeans or cargo pants to lean into the American streetwear aesthetic. The brown version reads more understated; the red version makes a bolder statement. Refer to the size chart: M fits a chest up to 120 cm, L up to 124 cm, and XL up to 128 cm.

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.
