A relaxed-fit blue and white striped shirt long sleeve style built for the modern casual wardrobe. Featuring a classic point collar, full button placket, and a chest patch pocket, this shirt blends American streetwear attitude with Japanese-inspired casual tailoring. The standout detail is the embroidered laurel crest with gothic "R" lettering on the chest, complemented by stacked text graphics reading "ISEEY IYKYK / CHASING DREAMS / LIMITLESS" — giving it a collegiate, off-duty energy. Back embroidery adds further depth with script and block lettering across the yoke.
Product Highlights
Vertical pinstripe woven fabric in navy blue or white colorways
Embroidered laurel wreath crest with gothic initial on the chest pocket
Graphic text embroidery on the back yoke for added streetwear detail
Classic point collar with full button-down front placket
Relaxed, boxy silhouette suitable for layering or wearing open over a tee
Buttoned barrel cuffs with clean finishing
Fit & Styling
This shirt is cut in a relaxed, slightly oversized silhouette that sits comfortably on the body without being boxy to the point of shapelessness. It works well worn open as a light layer over a plain white or black tee, or buttoned up for a smart-casual look. The collegiate crest embroidery makes it a natural pairing with straight-leg trousers, chinos, or denim. Available in navy blue pinstripe and white pinstripe — both versatile enough for spring and autumn wear. Refer to the size chart: M fits chest up to 120 cm, L up to 124 cm, XL up to 128 cm.
Product Details
Constructed from a woven cotton-blend fabric with a smooth, structured hand feel typical of pinstripe shirting. Material composition is approximately 65% Cotton, 35% Polyester, providing shape retention and easy care. The shirt features a single chest patch pocket, point collar, full button front, and long sleeves with single-button barrel cuffs. Embroidery is applied to both the front chest and back yoke. Available 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.
