This eye-catching long-sleeve jersey top blends anime-inspired graphic art with a sporty mesh panel construction. Featuring a V-neck collar with contrast orange trim, an all-over sky-blue polka-dot star print, and a bold anime character graphic on the front, this piece delivers a playful vibe-forward aesthetic suited for streetwear and casual outings alike. The back panel showcases a large "86" number graphic with wing motifs and the "MafaUntage" script, completing the retro sports jersey look.
Product Highlights
Anime character graphic print on front chest panel with star and wing details
Mesh fabric center panel for breathability, contrasted against a smooth blue polka-dot body
V-neck with orange ribbed collar and matching ribbed cuffs for a color-blocked finish
Oversized relaxed silhouette designed for a loose, comfortable fit
Back features large "86" number graphic with wing accents and brand script
Long sleeves with elasticated cuffs for a secure, clean finish
Fit & Styling
This top is cut in an oversized, relaxed fit — ideal for layering over a fitted tee or wearing solo with wide-leg trousers or joggers. The V-neck and contrast trim keep the look structured despite the loose body. Size up if you prefer an even more oversized drape; the chest measurements run generously. Best styled with neutral bottoms to let the graphic and color-block design take center stage.
Product Details
Fabric composition: approximately 90% Polyester, 10% Spandex — a lightweight, semi-sheer mesh-blend construction typical of sports jersey styles. Available in sky blue. Sizes M, L, and XL. Brand label: INS ERROR.

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.
