A bold American-vintage take on the classic flannel shirt, this oversized long-sleeve piece features a distressed Union Jack graphic on the chest, a contrast black star-panel inset on the front placket, and a cursive script print across the lower body. The washed plaid base gives the shirt an authentically worn-in, retro streetwear feel that pairs effortlessly with denim or cargo pants.
Product Highlights
Oversized relaxed silhouette with dropped shoulders for a laid-back street fit
Distressed Union Jack graphic printed on the left chest panel
Contrast black inset panel with large distressed star prints running vertically
Cursive script graphic across the lower front body adds retro personality
Classic point collar and full button-front placket with white buttons
Available in two colorways: navy/cream plaid and red/black plaid
Fit & Styling
This shirt is cut with a generous oversized fit — size up is not necessary. The boxy silhouette works well worn open over a plain white tee or buttoned up and tucked loosely into wide-leg jeans or cargo trousers. The navy/cream colorway leans cleaner and more versatile; the red/black reads louder and more punk-influenced. Both work as a layering piece over a long-sleeve tee in cooler months.
Product Details
Fabric composition is approximately 80% Cotton, 20% Polyester, giving the shirt a soft flannel-weight hand feel with light structure. The shirt features a curved hem, single-button cuffs, and a clean plain back panel. Available in sizes M through XXL.

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.
