A bold American varsity-inspired long-sleeve shirt rendered in crisp white, featuring an all-over polka-dot star print running down both sleeves, a lace-textured "77" graphic at the chest, a cursive "Racing Heart" script with heartbeat-and-airplane motif, and a gold crest emblem at the upper chest. The clean back panel lets the sleeve graphics do the talking, making this a versatile layering piece with a retro athletic edge.
Product Highlights
All-over black polka-dot star print on both sleeves for a bold varsity statement
Lace-pattern "77" chest graphic with decorative floral detailing
Cursive "Racing Heart" script with heartbeat line and airplane silhouette

Fit & Styling
This shirt is cut with a relaxed, slightly oversized silhouette suited for layering over a fitted base layer or wearing solo. The raglan sleeve construction gives the shoulders a comfortable, unrestricted feel. Pair it with straight-leg jeans or joggers for a campus-ready retro sports look. The chest width runs generously — size up if you prefer a more relaxed drape, or stay true to size for a standard athletic fit. Refer to the size chart for chest and sleeve measurements before ordering.

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.
