This oversized plaid flannel shirt jacket from Mafaer Vintage brings American retro style to life with a distressed wash finish and bold cartoon-inspired embroidery across the chest. Featuring a contrasting corduroy collar, button-front closure, and a relaxed boxy silhouette, it works equally well as a lightweight overshirt or a casual layering piece. Available in two colorways — a vivid sky blue plaid and an earthy washed brown plaid — each version carries the same vintage-worn character.
Product Highlights
Vintage wash treatment gives the plaid fabric an authentically worn, distressed appearance
Embroidered chest graphics including the "Mafaer Vintage" horse-and-star logo and a bold oval patch for a retro Americana feel
Contrasting corduroy collar in yellow (blue version) or charcoal grey (brown version) adds a tactile design detail
Relaxed oversized fit with dropped shoulders and a curved hem — easy to wear open over a tee or buttoned up
Long sleeves with button cuffs and a clean back panel with no back yoke seam
Available in sizes M, L, and XL with chest measurements from 116 cm to 124 cm (half-chest 58–62 cm)
Fit & Styling
The shirt is cut with an intentionally oversized, boxy silhouette — the shoulder width runs wide (59–61 cm) and the body length is generous (69–73 cm), making it ideal for wearing unbuttoned as a shacket over a graphic tee, hoodie, or slim-fit long sleeve. The curved hem and relaxed chest give it a streetwear-ready proportion. For a cleaner look, size down; for a more layered, oversized effect, stay true to size. The brown washed colorway pairs well with earth-tone bottoms, while the blue plaid works as a statement piece against neutral basics.
Product Details
Constructed from a brushed plaid flannel fabric — approximately 80% Cotton, 20% Polyester — with a soft, slightly napped surface that adds warmth without bulk. The contrasting collar is corduroy. Embroidery is applied directly to the chest panel. Button-front with dark resin buttons. Brand label at the back collar. Hand measurements may vary by 1–3 cm.

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.
