The Seakoff Retro Number 6 Long-Sleeve Jersey brings classic athletic energy into modern streetwear. Crafted from a 95% polyester and 5% spandex blend, the fabric delivers a glossy, smooth finish that catches the light and commands attention. Available in white, pink, and black, each colorway features a bold oversized "6" graphic on the front, making a statement that is equal parts nostalgic and fashion-forward.
Design Details Worth Noticing
The jersey features a split V-neckline with a contrast collar in black or white depending on the colorway, giving it an authentic retro sports feel. Black contrast piping runs along the raglan seams and sleeves, adding definition to the relaxed silhouette. A layered sleeve construction creates the look of a jersey worn over a long-sleeve base layer, all built into one piece for effortless styling. Small gothic-script branding sits at the chest, keeping the look clean and intentional.
Relaxed Fit Built for Layering
The relaxed silhouette sits comfortably over hoodies, turtlenecks, or fitted tees, making it a versatile layering piece for streetwear outfits, casual days out, or sport-inspired looks. The lightweight stretch fabric moves with you without feeling restrictive. Sizes range from S to XXL with detailed measurements available to help you find the right fit.

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.
