A relaxed, Korean-inspired overshirt built around a bold plaid check and a diamond quilted stitch pattern that runs across the entire body. Intentional distressing — frayed rips scattered across the front, back, and hem — gives this washed flannel shirt a worn-in, streetwear-ready character that pairs equally well with wide-leg denim or layered under a heavier jacket.
Product Highlights
All-over diamond quilted stitching adds subtle texture and structure to the lightweight plaid fabric
Intentional distressed rips at the chest, hem, and back for a lived-in aesthetic
Dual chest flap pockets with snap buttons for a utilitarian, workwear-influenced detail
Washed finish softens the fabric and creates a natural gradient effect across the plaid
Dropped shoulders and an oversized silhouette designed for a relaxed, campus-ready fit
Available in two colorways: warm rose-red plaid and navy-cream plaid
Fit & Styling
This shirt is cut with a generous, boxy oversized fit — the dropped shoulders and wide chest measurement make it ideal to wear open as a lightweight overshirt over a plain tee or hoodie, or buttoned up as a standalone top. The curved hem sits slightly longer at the back. Sizing runs large; refer to the size chart for chest and shoulder measurements before ordering. Works well with straight or wide-leg trousers, cargo pants, or washed denim for a clean, effortless streetwear look.
Product Details
Fabric: approximately 100% cotton woven plaid with a washed treatment. Closure: full button-down front with snap-button chest pockets. Features: diamond quilted topstitching throughout, intentional distressed fraying, dual flap chest pockets, curved hem, snap cuffs. Available in Red Plaid and Dark Navy Plaid. Sizes S–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.
