This oversized washed denim blazer jacket blends the structure of a classic blazer with the relaxed ease of denim outerwear. Cut from 100% cotton denim in a faded grey-black wash, it delivers a lived-in, vintage aesthetic that works equally well dressed up or down. The acid-wash finish gives each piece a subtly unique character, making it a versatile layering staple for any wardrobe.
Product Highlights
Relaxed oversized silhouette with dropped shoulders for an effortlessly cool fit
Notched lapel collar and two-button front closure in blazer styling
Two large patch pockets at the hem for a utilitarian, streetwear-ready look
Chest welt pocket adds a tailored detail to the casual denim construction
Acid-washed and garment-dyed finish creates a vintage, worn-in appearance
100% cotton denim fabric — breathable, durable, and softens with wear
Fit & Styling
This jacket is cut with an intentionally oversized, boxy fit — the model is shown wearing a size that sits well off the shoulders, hitting at the hip. It layers naturally over a cropped white shirt or tee and pairs effortlessly with wide-leg grey denim for a tonal, relaxed outfit. The structured lapels keep the look polished enough for casual outings, while the patch pockets and washed finish lean into streetwear and vintage-inspired styling. Unisex in proportion, it suits a wide range of body types. Size up if you prefer an even more exaggerated drop-shoulder look; size down for a slightly more fitted silhouette.

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.
