A clean, versatile plaid button-up shirt built for everyday casual wear. Featuring a classic grid check pattern in a relaxed oversized silhouette, this long sleeve shirt draws from American casual and Japanese streetwear aesthetics for an effortlessly put-together look. Available in off-white and navy, it works equally well worn open over a tee or buttoned up solo.
Product Highlights
Classic plaid check pattern in a two-tone grid weave
Relaxed oversized fit with dropped shoulders for a laid-back silhouette
Point collar with a clean, unfussy construction
Single chest patch pocket for a utilitarian detail
Dark snap-style buttons running the full placket and cuffs
Curved hem for easy untucked styling
Fit & Styling
This shirt is cut with an oversized, boxy fit — size down if you prefer a more standard relaxed fit, or stay true to size for the full dropped-shoulder look. The curved hem sits cleanly over slim trousers, chinos, or straight-leg denim. Layer it open over a plain white or black tee for a casual streetwear outfit, or button it fully for a smart-casual clean fit. The off-white colorway pairs well with neutral tones; the navy reads more structured and works well into autumn layering.
Product Details
Constructed from a lightweight cotton-blend woven fabric with a soft, slightly textured hand feel typical of plaid flannel-style shirting. Material composition: 80% Cotton, 20% Polyester. Available in sizes M through XXL. Two colorways: Off-White and Navy.

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.
