A bold American retro-inspired long-sleeve tee featuring a large star graphic, varsity-style lettering, and the standout detail of faux-layered striped sleeves. The body carries a striking "New World" and "Ahofero" chest print with EST. 1987 collegiate motifs, while the contrast blue and grey horizontal-striped sleeve panels create the illusion of a layered look in a single garment. Available in heather grey and burgundy wine red.
Product Highlights
Faux double-layer design: solid body with contrast horizontal-striped sleeve panels for a layered look
Large embroidered-style star graphic with varsity arc lettering on the chest
Collegiate details: "EST. 1987", USA badge, and "AND THIS IS OUR FUTURE" slogan print
Relaxed oversized silhouette with a classic crew neckline
Available in heather grey and burgundy wine red colorways
Sizes M–XL with generous chest and shoulder measurements for an easy oversized fit
Fit & Styling
This tee is cut in a relaxed, boxy oversized fit that sits comfortably on the shoulders and through the body. The dropped shoulder and wide chest make it ideal for layering over a long-sleeve base or wearing solo. Pair it with straight-leg jeans, cargo pants, or wide-leg trousers for a campus-ready or streetwear look. The striped sleeves add visual interest without requiring any extra layering effort. Fits true to an oversized sizing — those preferring a closer fit may size down.
Product Details
Fabric: approximately 100% cotton jersey body with a cotton-blend striped knit sleeve panel. The heather grey and burgundy wine red colorways share the same blue-grey striped sleeve construction. Chest graphic uses a combination of raised print and flat screen-print techniques. Crew neckline with ribbed collar. Measurements are taken flat; a 1–3 cm variance is normal due to hand measurement.

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.
