The Seakoff Black Long Sleeve Graphic Tee features a bold collage-style print that combines layered imagery, contrast typography, and hand-scrawled text elements inspired by underground and grunge culture. Phrases like "Think Outside the Box" and "The Mind Mode" are woven into the artwork, giving the piece a raw, expressive character that stands apart from standard streetwear designs.
Intentionally Worn, Deliberately Designed
Crafted from 100% cotton, this oversized black long sleeve graphic tee carries a washed finish that deepens the vintage feel. Deliberately placed distressed holes appear across the body and sleeves, creating a broken-in look that feels authentic rather than manufactured. The ribbed crew neck and long-sleeve construction keep the silhouette clean while the raw distressed details add visual tension throughout.
A Versatile Layering Piece
The relaxed oversized fit makes this graphic tee an easy layering option over a longline undershirt or under an open jacket. Pair it with cargo pants, wide-leg denim, or shorts for a complete streetwear look. The unisex design and black colorway make it a reliable go-to for everyday casual wear across seasons.

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.
