This oversized long sleeve tee delivers a bold American streetwear aesthetic through a clever faux two-piece construction — a printed graphic panel layered over a solid long sleeve base, creating the illusion of a vest worn over a shirt. The front is covered in a distressed vintage-style graphic featuring heraldic crests, star rows, and the "mfour" logo rendered in a worn, retro print. Available in yellow/white and black colorways, each with its own distinct mood.
Product Highlights
Faux two-piece design: graphic-printed panel sewn onto a contrasting long sleeve base for a layered look in one garment
Distressed vintage crest and star graphics across the full front panel
Relaxed oversized silhouette with a classic crew neckline
Ribbed cuffs at the sleeve hem for a clean, structured finish
Available in yellow/white colorblock and all-black versions
Curved panel seaming on the back adds visual structure and dimension
Fit & Styling
Cut in a relaxed, oversized fit that sits comfortably on the shoulders and through the body. The faux layered construction adds visual bulk without extra weight, making it easy to wear solo or over a lightweight tee. Pair with straight-leg jeans or cargo pants and chunky sneakers to lean into the retro streetwear vibe. The yellow/white version makes a louder statement; the black reads more versatile for everyday wear. Sizing runs in M, L, and XL — refer to the chest and length measurements to find your best fit.

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.
