A laid-back essential for transitional dressing, this men's long sleeve striped shirt delivers an effortlessly relaxed silhouette with a Japanese-inspired casual aesthetic. Vertical pinstripes run the full length of the garment, creating a clean, elongating visual on a generously cut, drop-shoulder frame. Available in navy and off-white, it works equally well as a standalone top or an open overshirt layered over a tee.
Product Highlights
Oversized, boxy silhouette with dropped shoulders for a relaxed, high-street fit
Vertical pinstripe pattern in classic navy or off-white colorways
Point collar with a full button-through placket and dark contrast buttons
Single chest patch pocket adds a utilitarian detail
Long sleeves with buttoned cuffs for a neat, polished finish
Slightly curved hem for versatile tucked or untucked wear
Fit & Styling
This shirt runs oversized by design — the chest measurement starts at 122 cm in size M, making it ideal for a relaxed, unstructured look. Wear it open over a plain white or black tee with straight-leg trousers or wide-leg pants for a clean streetwear outfit. The off-white version pairs well with neutral earth tones, while the navy reads sharper alongside dark denim or chinos. Suitable for spring and autumn layering.
Product Details
Constructed from a lightweight woven fabric, this shirt is composed of approximately 70% Cotton and 30% Polyester, giving it a soft hand feel with light structure and easy care. The pinstripe weave has a subtle texture visible across the body of the shirt. 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.
