The Seakoff Union Graphic Long Sleeve Tee brings bold British iconography into everyday streetwear. A large Union flag graphic sits front and center, paired with printed text accents across the chest and sleeves for a layered, editorial feel. The muted, heather-grey colorway keeps the look versatile without sacrificing visual impact.
Relaxed Fit Built for Daily Wear
Cut in a relaxed silhouette with a ribbed crew neckline, this long sleeve tee moves comfortably through any setting. Made from 100% cotton, the fabric feels soft against the skin and holds its structure wear after wear. The dropped shoulders and easy through-body fit make it a natural layering piece over basics or under outerwear.
Easy to Style, Hard to Ignore
Whether worn with wide-leg denim and chunky boots for a full streetwear look or thrown over a simple outfit for an effortless statement, this tee adapts. The minimalist color palette and graphic-forward design make it a go-to piece for those who want expressive style without overthinking it. Available in sizes S through 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.
