This boxy button up shirt from Seakoff redefines everyday shirting with a bold, forward-thinking silhouette. A diagonal button placket runs from the stand collar down to a pointed hem, creating a clean asymmetric line that sets this piece apart from conventional button-ups. The structured stand collar frames the neckline with quiet authority, lending a tailored, almost architectural quality to the overall look.
Crafted from 100% Cotton for All-Day Comfort
Made entirely from 100% cotton, this shirt offers breathable, lightweight wear suited to warmer seasons or layering in transitional weather. The fabric carries a subtle textured weave visible across the body, adding depth without disrupting the minimalist aesthetic. Sleeves are designed with a rolled cuff detail, giving the shirt a relaxed yet intentional finish that works equally well dressed up or kept casual.
Versatile Styling for Modern Wardrobes
Available in a fine houndstooth grey and a solid black, both colorways pair effortlessly with tailored trousers, wide-leg pants, or dark denim. The boxy, structured silhouette sits comfortably off the body without excess volume. Whether worn open as a layering piece or fully buttoned for a cleaner look, this shirt transitions naturally from street to studio to social settings.
Frequently Asked Questions
Does the shirt close fully when all buttons are fastened?
Yes. The asymmetrical placket buttons fully from collar to hem, allowing the shirt to be worn completely closed or partially open for a more relaxed drape.
Is the grey colorway a solid or patterned fabric?
The grey version features a fine micro-check or houndstooth weave, while the black version is a solid fabric. Both share the same cut and construction.

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.
