This long sleeve polo shirt brings American streetwear attitude to an easygoing silhouette. Built with a relaxed, oversized fit and a contrast-color polo collar, it features a distressed, washed-out finish that gives each piece a lived-in, vintage feel. The front is covered in a bold graphic collage — a screen-printed figure, gothic architecture, and hand-scrawled phrases like "Hardest to Love," "Too Late," and "Can't Be Alone Again" — making it a statement piece straight out of the box.
Product Highlights
Oversized relaxed fit with a classic polo collar and two-button placket
Contrast-color collar detail — cream on washed green, pink on washed grey
Distressed washed finish for a vintage, worn-in aesthetic
Full-front graphic collage with screen-printed figure, architecture, and text elements
Long sleeves with clean, unadorned back panel for a balanced look
Available in two washed colorways: Washed Grey and Washed Green
Fit & Styling
The oversized long sleeve polo shirt is cut generously across the chest and shoulders, making it ideal for layering over a plain tee or wearing solo with wide-leg trousers or cargo pants. The dropped shoulders and boxy body suit those who prefer a relaxed, streetwear-forward silhouette. Refer to the size chart: size M measures 50 cm shoulder width, 110 cm chest, 64 cm sleeve length, and 66 cm body length. Size up if you prefer an even more exaggerated drape, or size down for a slightly more fitted look within the oversized cut.

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.
