A sharp, versatile blazer jacket built for men who want polished style without the formality of a full suit. This single-breasted design features four ornate silver-tone buttons down the front, a notched lapel, a chest welt pocket, and two flap pockets at the hem. The structured, tailored silhouette is achieved through three-dimensional pattern cutting, giving the jacket a clean, fitted shape that sits neatly on the shoulders and through the torso. A center back vent adds ease of movement and a refined finishing detail.
Product Highlights
Single-breasted four-button front closure with decorative silver-tone coin buttons
Notched lapel with a classic, slightly relaxed collar stance
Structured tailored fit achieved through three-dimensional pattern cutting
Chest welt pocket and two flap hip pockets for functional detail
Center back vent for ease of movement and a clean rear silhouette
Solid black colorway that transitions easily from casual to smart-casual occasions
Fit & Styling
This blazer is cut in a fitted, body-conscious silhouette — not oversized, not boxy. The shoulder seam sits at the natural shoulder point, and the body tapers slightly through the waist for a contemporary slim-fit appearance. It works well over a plain crew-neck tee for an American casual look, or layered over a mock-neck or shirt for smarter occasions. Refer to the size chart: size M measures 64 cm in length, 114 cm chest, 48 cm shoulder width, and 61 cm sleeve length. Size up if you prefer a relaxed fit or plan to layer underneath.
Product Details
Fabric composition: approximately 75% Polyester, 25% Rayon — a smooth, structured mid-weight woven blend that holds its shape and resists creasing, consistent with the fabric appearance and drape visible in the product images. Color: Black. Closure: Four decorative silver-tone buttons. Pockets: One chest welt pocket, two front flap pockets. Back detail: Center vent. Available in sizes M, L, XL, and 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.
