The Seakoff Long Sleeve Striped Shirt is built for effortless everyday wear. Crafted from a soft 70% acrylic, 19% nylon, and 3% spandex blend, it delivers a gentle stretch and comfortable drape that moves with you throughout the day. Available in a warm oatmeal stripe and a deep charcoal stripe, both colorways carry a clean, understated aesthetic that works across seasons.
Thoughtful Construction and Relaxed Silhouette
Horizontal stripes run across a slightly oversized body with dropped shoulders and a structured center seam that defines the front panel. The wide, voluminous sleeves taper into gathered elasticated cuffs, giving the shirt a modern balloon-sleeve shape without sacrificing ease of movement. A minimal crew neckline and concealed placket keep the look polished and free of unnecessary hardware.
Versatile Everyday Styling
This striped shirt pairs naturally with straight-leg denim, cargo pants, or wide-leg trousers for a balanced, relaxed outfit. Its neutral stripe palette makes it easy to layer under outerwear or wear alone as a standalone top. Whether you are dressing for a casual weekend or a low-key workday, this piece adapts without effort.

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.
