The Seakoff blue plaid button up shirt is built for those who treat getting dressed as a creative act. A fine blue and grey check base sets a classic foundation, while collage-style graphic patches scattered across the front bring an unmistakable DIY, zine-culture energy. A minimalist typography print reading across the chest ties the visual story together without overpowering the overall look.
Relaxed Fit with Thoughtful Construction
Cut in a relaxed streetwear silhouette, this shirt works equally well worn open over a tee or buttoned up as a standalone layer. The structured point collar and clean button-up front closure keep the piece grounded, while the slightly dropped shoulders and roomy chest allow for easy, comfortable movement throughout the day. The back panel is clean and undecorated, letting the front artwork take centre stage.
100% Cotton Comfort
Made entirely from cotton, the fabric is soft and breathable, making this shirt a practical choice for daily wear across multiple seasons. The plaid weave adds subtle texture and depth without feeling heavy. Whether styled with slim trousers, cargo pants, or layered under a jacket, this piece adapts easily to a range of streetwear and casual outfits.

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.
