The Seakoff Boxy Short Sleeve Shirt delivers a distinctive industrial-street aesthetic through its carefully crafted panel seam construction. Visible seam lines run vertically from the shoulder through the chest, creating a structured, architectural silhouette that sets this tee apart from standard basics. A subtle distressed finish along the shoulder seams adds intentional worn-in character without compromising the garment's integrity.
Vintage Washed Finish for Effortless Style
Each boxy tee undergoes a vintage wash process that produces a naturally faded, lived-in tone. Available in washed olive green and washed black, both colorways carry a muted, sun-bleached depth that pairs seamlessly with cargo pants, relaxed denim, or layered outerwear. The mock crew neckline sits slightly higher than a standard crewneck, lending a clean, modern edge to the overall silhouette.
Everyday Comfort in 100% Cotton
Crafted from 100% cotton, this boxy short sleeve shirt offers breathable, all-day comfort in a relaxed oversized fit. The dropped shoulders and boxy cut allow for easy movement while maintaining a polished, intentional look. Raw-edge hem details and structured shoulder panels reinforce the garment's premium streetwear positioning without relying on logos or graphics.

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.
