A relaxed-fit long sleeve crew neck shirt built around a bold football-jersey aesthetic. The front features large serif lettering reading "Lock in Blegchn" alongside a decorative crest badge and script logo, while the back carries a monogram graphic and dual number "77" print — giving it the look of a vintage European football kit reimagined as streetwear. Available in warm sand beige and deep navy.
Product Highlights
Oversized, relaxed silhouette with dropped shoulders for a casual street-ready fit
Football-jersey inspired front graphic with serif text, crest badge, and script emblem
Back features a bold monogram logo and "77" number print
Ribbed crew neckline and ribbed cuffs for a clean, structured finish
Available in two versatile colorways: sand beige and navy

Fit & Styling
This shirt runs with an intentionally oversized, boxy fit — size down if you prefer a more relaxed-but-fitted look, or stay true to size for a full streetwear drop. Pair with slim or tapered trousers and chunky sneakers to balance the volume. The neutral beige works well with earth tones and black bottoms, while the navy reads cleanly against grey or white. Suitable for casual outings, street photography, and relaxed social settings.

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.
