This oversized black long sleeve tee delivers a bold American street-rock aesthetic through a clever faux two-piece construction. A short-sleeve waffle-knit outer shell sits over a white long-sleeve inner layer featuring contrast black side stripes, creating a layered look in a single garment. The large back graphic — a distressed iron-cross motif with old-English lettering reading "HAVE MT GROWING 99" — makes an immediate statement, while a matching chest patch keeps the front clean and intentional.
Product Highlights
Faux two-piece design: black oversized short-sleeve shell over a white striped long-sleeve underlayer — one piece, zero hassle
Large back iron-cross graphic with distressed old-English typography for a rock and streetwear edge
Matching small chest patch graphic for a cohesive front-to-back design
Relaxed, boxy oversized silhouette with a crew neckline
Contrast black side stripes on the white underlayer sleeves add a sporty detail
Available in sizes M, L, and XL with generous chest measurements (132–140 cm) for a true oversized fit
Fit & Styling
Cut with a wide, boxy body and dropped shoulders, this tee is designed to be worn loose. The chest measurements run large — size M measures 132 cm around the chest — so this is a true oversized silhouette rather than a relaxed regular fit. Pair it with slim or straight-leg cargo pants or jeans to balance the volume. The black-and-white colorway and graphic print work naturally with chunky sneakers, boots, or skate shoes. Ideal for those who lean into high-street, rock-influenced, or Y2K-adjacent aesthetics.
Product Details

Graphic: distressed iron-cross back print and chest patch in old-English lettering. Fabric: 100% Cotton. Sizes available: M, L, 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.
