A relaxed American-vintage inspired plaid button-up shirt built for everyday wear. Featuring an all-over tartan check pattern, a classic point collar, and a chest patch pocket with a bold embroidered logo graphic, this long-sleeve shirt brings a casual streetwear edge to a timeless silhouette. Available in three colorways — light blue, brown, and black — it transitions easily from spring layering to standalone autumn wear.
Product Highlights
All-over plaid tartan check pattern in three distinct colorways
Embroidered logo graphic on the chest pocket for a streetwear-ready detail
Matching embroidered text graphic across the upper back yoke
Classic point collar with a full button-front placket
Long sleeves with buttoned cuffs for a clean, polished finish
Relaxed oversized fit suitable for layering or wearing open over a tee
Fit & Styling
This shirt is cut with a relaxed, slightly oversized silhouette that sits comfortably on the shoulders and through the body. It works well worn open as a light overshirt over a plain tee, or buttoned up for a more put-together casual look. The plaid pattern and logo embroidery give it a Japanese streetwear-influenced aesthetic that pairs naturally with straight-leg jeans, cargo pants, or chinos. Sizing runs generously — refer to the size chart and consider your preferred fit when choosing between sizes.

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.
