The Questionmark 3 Classic Black Denim Jacket is built for those who wear their identity on their sleeve — literally. Constructed from 100% cotton denim, this heavyweight trucker-style jacket delivers a structured, durable silhouette that holds its shape season after season. White contrast stitching runs throughout, sharpening every seam and giving the dark indigo shell a bold, workwear-rooted edge.
Details That Set It Apart
Up front, dual flap chest pockets with copper button closures add a utilitarian touch that nods to classic American denim heritage. The full button-front placket uses the same copper hardware for a cohesive, refined finish. Flip the collar back and you'll find a leopard-print inner lining — a deliberate contrast to the jacket's clean exterior that rewards those who look closer. The back panel features an embroidered arc-style "Questionmark 3" graphic, making this piece unmistakably its own. A cropped fit keeps the proportions modern and easy to layer over hoodies or under heavier outerwear.
How to Wear It
Pair this jacket with straight-leg denim for a tonal double-denim look, or throw it over a graphic tee and cargo pants for an effortless streetwear outfit. The cropped length works equally well tucked into high-waist trousers or worn open over a longline layer. Available in sizes S through XL — refer to the size guide below for exact measurements.

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.
