This striped long sleeve t-shirt brings a classic American streetwear aesthetic to your everyday wardrobe. Featuring bold horizontal black-and-white stripes across a relaxed, oversized silhouette, it pairs the timeless nautical stripe pattern with a modern boxy cut. Available in two colorways — a dark navy-black base and a clean off-white base — both versions share the same multi-stripe construction with a small embroidered logo detail above the chest pocket.
Product Highlights
Horizontal multi-stripe pattern in contrasting black and off-white tones
Relaxed oversized fit with a clean crew neckline
Long sleeves with matching stripe detail throughout
Small chest pocket with embroidered brand logo
Available in two colorways: Black base and Cream/Off-White base
Versatile styling suitable for casual, streetwear, and layered looks
Fit & Styling
This shirt is cut in a relaxed, oversized silhouette that sits comfortably on the shoulders with a slightly dropped shoulder seam and a straight hem. It works well worn alone or layered under an open jacket or overshirt. The crew neck and clean stripe pattern make it easy to pair with straight-leg jeans, chinos, or casual trousers. The black colorway leans darker and more graphic, while the cream colorway offers a lighter, more vintage-inspired feel. Sizing runs generously — refer to the size chart for chest and length measurements before ordering.
Product Details
Constructed from a medium-weight cotton-blend jersey, estimated at 95% Cotton and 5% Elastane, giving the fabric a structured feel with slight stretch for ease of movement. The stripe pattern is knitted directly into the fabric rather than printed, contributing to the textured surface visible in the product images. Brand label at the back neck. Available in sizes M through XXL.

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.
