Old-School Jersey Energy, Reimagined for the Streets
The Seakoff Energy 11 Vintage Jersey Tee takes classic American sportswear and rebuilds it for modern street culture. The centrepiece is a large distressed "11" graphic printed in cracked white ink across the chest, giving the shirt an authentically worn, vintage feel. Above it, bold "ENERGY" lettering in a retro athletic font adds to the throwback aesthetic without feeling costume-like.
Design Details That Set It Apart
White contrast piping traces the curved raglan panel seams from shoulder to hem, adding visual structure and a genuine jersey-inspired silhouette. The sleeves feature double stripe detailing in a matching distressed print, tying the whole look together. A woven label sits at the back collar, and the V-neckline keeps the sportswear reference clean and intentional. The drop-shoulder construction and oversized silhouette create a relaxed, effortless fit that works equally well tucked, untucked, or layered.
How to Wear It
Pair this tee with wide-leg cargo trousers and chunky sneakers for a full streetwear look, or keep it simple with straight-leg denim and low-top trainers. The all-black and white colourway makes it easy to style across seasons. Made from 100% cotton, it offers comfortable all-day wearability with a substantial feel.

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.
