This purple football-inspired jersey tee from M.T.9.9 blends American sports aesthetics with streetwear sensibility. Built from a two-fabric construction — a smooth satin-finish upper yoke and a breathable mesh lower body — the shirt features a bold embroidered "09" number patch on the front, gold and red stripe trim at the sleeves, a ribbed V-neckline, and woven brand badges at the chest and sleeve. It's a standout v neck t shirt designed for warm-weather wear with a relaxed, oversized silhouette.
Product Highlights
Bold embroidered "09" number patch on the front chest panel
Two-tone fabric construction: smooth satin-finish yoke panel paired with perforated mesh lower body for ventilation
Gold and red stripe sleeve cuffs for a classic American football jersey look
Ribbed V-neckline with clean rib trim finish
Woven brand badge at left chest and embroidered patch at right sleeve
Relaxed, boxy oversized fit suitable for layering or wearing solo
Fit & Styling
This jersey runs with a deliberately oversized, boxy silhouette — the shoulder width and chest measurements are generous, making it ideal for a relaxed streetwear look. Pair it with slim joggers or cargo shorts to balance the volume. The short sleeve length and mesh lower body keep it breathable for summer outings, festivals, or casual sport-inspired outfits. Refer to the size chart: S fits a 122 cm chest, M fits 126 cm, and L fits 130 cm. If you prefer a closer fit, consider sizing down.
Product Details
The jersey is constructed from approximately 90% polyester and 10% spandex — a blend typical of sport-mesh and satin-finish athletic jerseys that supports quick-dry performance and shape retention. The upper yoke uses a smooth woven polyester with a subtle sheen, while the lower body and sleeves use an open-hole mesh polyester for airflow. Color: Purple. Available in sizes S, M, and L. Brand: M.T.9.9.

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.
