A casual-cool take on the classic button-up, this long-sleeve shirt blends the structure of a woven shirt with the laid-back attitude of a hoodie. Vertical blue-and-white pinstripes run the full length of the garment, while a drawstring hood, front button placket, and boxy silhouette give it a distinctly relaxed, Japanese-influenced aesthetic that works equally well layered or worn on its own.
Product Highlights
Hooded button-up shirt with navy drawstring cords for adjustable fit around the hood
Classic blue-and-white vertical pinstripe woven fabric with a clean, crisp appearance
Relaxed boxy silhouette with dropped shoulders for an effortless oversized look
Back box pleat adds volume and ease of movement without bulk
Buttoned barrel cuffs and a full-length front button placket for a polished finish
Small embroidered logo patch at the left chest for subtle branding detail
Fit & Styling
Cut in a loose, oversized fit that sits comfortably on the shoulders and through the body. The hem falls at hip length, making it easy to wear untucked over slim trousers, chinos, or denim. The relaxed drop-shoulder construction means sizing down is not necessary — the generous cut is intentional. Style it open over a plain white tee for a layered clean-fit look, or button it up fully and let the hood frame the outfit. Works well for spring and autumn layering.
Product Details
Fabric: 100% Cotton woven poplin, offering a lightweight, breathable hand feel with a subtle sheen typical of yarn-dyed stripe shirting. Available in Blue/White Stripe. Sizes S through XL; see size chart for chest, length, shoulder, and sleeve measurements before ordering.

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.
