Fit & Styling
Cut with a relaxed, boxy silhouette and dropped shoulders, this shirt is designed to be worn untucked for a casual, effortless look. The generous chest and shoulder measurements make it ideal for layering over a basic tee or wearing open as a light overshirt. Pair it with straight-leg trousers or wide-leg denim to complement the vintage vibe. Size M measures 69 cm in length, 116 cm chest, 59 cm shoulder width, and 54 cm sleeve length — size up if you prefer an even more oversized fit.

This striped shirt for men is crafted from a lightweight woven fabric composed of approximately 100% cotton, giving it a soft, breathable hand feel well-suited to transitional seasons. The shirt features a full button-front closure, a single chest patch pocket, and button-fastened cuffs. The clean back panel is free of seams or graphics, keeping the stripe pattern uninterrupted. Offered in sizes M, L, and XL.

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.
