A relaxed, American-inspired take on the classic plaid shirt, this long-sleeve button-up features a fine gingham base layered with horizontal stripe jacquard detailing for a textured, streetwear-ready look. Available in black and blue colorways, it suits a wide range of casual and smart-casual outfits across spring and autumn seasons.
Product Highlights
Fine gingham check fabric with repeating horizontal stripe pattern for added visual depth
Oversized, boxy silhouette designed for a relaxed, laid-back fit
Classic point collar with full button-front placket
Single chest patch pocket adds a utilitarian detail
Long sleeves with single-button barrel cuffs
Available in black/white and blue/white plaid colorways
Fit & Styling
This shirt is cut with a generous, drop-shoulder oversized fit — size down if you prefer a more structured look, or wear true to size for the intended relaxed silhouette. The curved hem sits at hip length, making it easy to wear untucked over straight-leg jeans, cargo pants, or wide-leg trousers. Layer it open over a plain tee for a casual streetwear look, or button it up fully for a cleaner, smart-casual aesthetic. Both the black and blue versions pair well with neutral bottoms.
Product Details
Constructed from a woven cotton-blend fabric that gives the gingham check its crisp structure and the stripe detailing its subtle texture. The material composition is approximately 65% Cotton, 35% Polyester, providing a balance of breathability and shape retention. The shirt features a blue woven brand label at the inner collar. Sizes available: M, L, XL, XXL. Please refer to the size chart for chest, shoulder, sleeve, and length measurements before ordering.

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.
