A retro-inspired long-sleeve striped shirt built for relaxed, streetwear-ready dressing. The body features a speckled yarn-dyed horizontal stripe fabric in either a cream-and-black or purple-and-green colorway, with a contrasting ribbed crew neck in olive or purple. The chest carries a bold Korean-script embroidered graphic alongside cloud illustrations, the text "AMNI DAY" and a chenille "97" patch, giving the piece a distinctly nostalgic American collegiate feel.
Product Highlights
Horizontal stripe pattern woven from speckled, multi-fleck yarn for a vintage texture
Contrasting ribbed crew neckline in olive green or purple depending on colorway
Embroidered Korean-script graphic with cloud motif and chenille number patch on chest
Relaxed oversized silhouette with dropped shoulders and a boxy body
Long sleeves with ribbed cuffs for a clean, structured finish
Available in two colorways: Cream (with olive trim) and Purple (with purple trim)
Fit & Styling
This shirt is cut in a roomy, oversized fit that sits comfortably on the body without feeling shapeless. The dropped shoulder seam and wide chest make it ideal for layering over a long-sleeve base tee or wearing alone with wide-leg trousers or cargo pants. The boxy hem falls at the hip, making it easy to tuck partially or leave untucked. Sizing runs true to the measurements provided — those preferring a more fitted look should consider sizing down one size.
Product Details
Fabric composition: approximately 80% Cotton, 20% Polyester, constructed from a speckled slub-yarn jersey with woven stripe detailing. Crew neck with contrasting ribbed collar. Embroidered and chenille patch graphics on chest. Long sleeves with ribbed cuffs. Available in sizes S through XL. Two colorways: Cream / Olive and Purple.

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.
