A relaxed oversized flannel shirt jacket built for the American vintage aesthetic. Woven in a bold multi-color plaid, this hooded overshirt features a washed, faded finish that gives each piece a lived-in character. The raw frayed hem adds a deliberate distressed edge, while the attached hood and button-front placket keep the silhouette clean and versatile. Available in two colorways — sage green and dusty purple — each with contrasting yellow, burgundy, and white plaid lines.
Product Highlights
Attached hood integrated into the shirt collar for a relaxed layered look
Washed and faded plaid fabric with a vintage, worn-in feel
Raw, frayed hem at the bottom for a distressed streetwear detail
Button-front closure with a single chest patch pocket
Oversized boxy silhouette with dropped shoulders and wide sleeves
Available in sage green plaid and dusty purple plaid colorways
Fit & Styling
This shirt jacket runs oversized with a boxy, relaxed fit — ideal for wearing open over a graphic tee or hoodie, or buttoned up as a standalone layer. The dropped shoulders and wide chest give it a Korean clean-fit streetwear feel. Pair with straight-leg jeans or cargo pants to complement the vintage American plaid aesthetic. Refer to the size chart: chest measurements range from 134 cm (S) to 146 cm (XL), making this a true oversized piece across all sizes.
Product Details
Material: approximately 100% Cotton flannel, brushed for a soft hand feel. The fabric is pre-washed to achieve the faded gradient tone visible across the plaid pattern. Frayed hem is intentional and part of the design. Button cuffs. Small woven brand label on the chest pocket. Sizes available: S, M, L, XL.

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.
