This oversized long-sleeve button-up shirt features a distinctive washed plaid pattern in muted steel blue and white, with a crinkle-textured finish that gives it a lived-in, vintage-inspired character. Cut with a relaxed, drop-shoulder silhouette and a curved hem, it works equally well as a standalone top or an open layering piece.
Product Highlights
Washed plaid print in steel blue and white with an all-over crinkle texture for a vintage aesthetic
Relaxed oversized fit with dropped shoulders and a curved high-low hem
Classic point collar and full button placket with tonal dark buttons
Single chest patch pocket adds a workwear-inspired utility detail
Long sleeves with single-button cuffs for a clean, unfussy finish
Unisex-leaning silhouette suitable for a wide range of body types and styling approaches
Fit & Styling
The shirt is cut generously across the chest and shoulders — the size chart shows a chest measurement of 121–127 cm across sizes S–XL — making it ideal for an intentionally oversized look. Pair it with olive cargo shorts or wide-leg trousers as shown, or wear it open over a fitted tee. The muted blue palette pairs naturally with earth tones, khaki, and denim. For a more polished take, tuck the front hem into high-waisted trousers and add a crossbody bag.

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.
