A classic plaid button-up shirt built for easy, versatile dressing. Featuring a small-scale check pattern in a relaxed, slightly oversized silhouette, this long-sleeve shirt brings a clean retro-casual aesthetic that works equally well tucked into trousers or worn open over a tee. Available in a warm wheat tone and a rich navy blue, it suits a wide range of outfits across spring and autumn.
Product Highlights
Small-scale plaid check pattern in a classic two-color palette
Relaxed, boxy silhouette with room through the chest and shoulders
Point collar with a clean, structured lay
Full button-front placket with matching buttons
Left chest patch pocket for a functional, casual detail
Long sleeves with single-button barrel cuffs
Fit & Styling
This shirt is cut with a relaxed, oversized fit — the chest measurement runs generously, making it ideal for layering over a lightweight crewneck or wearing unbuttoned as an overshirt. The dropped shoulders and boxy body give it a Japanese casual streetwear feel. For a clean look, size down if you prefer a more standard fit; stay true to size for the intended relaxed drape. Pair with slim chinos, straight-leg jeans, or casual trousers. Works well with neutral tones to let the plaid pattern stand out.
Product Details
Material: 100% Cotton woven fabric, offering a soft, breathable hand feel with light structure. The plaid is woven into the fabric rather than printed, giving it depth and texture. Available in Wheat (light neutral check) and Navy Blue (dark indigo check). Sizes M through XXL; see size chart for chest, length, shoulder width, and sleeve length measurements.

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.
