This oversized long-sleeve waffle-knit shirt channels American street rock and hip-hop aesthetics through a bold iron cross graphic printed across the chest in distressed white ink. Old English lettering reading "Have Growing MT99" fills the cross motif, while both sleeves carry additional gothic script prints running from shoulder to cuff. Available in black and heather grey, the ribbed waffle texture adds visual depth and a relaxed, heavyweight feel suited to streetwear layering.
Product Highlights
Large distressed iron cross graphic on the chest with Old English gothic lettering
Gothic script sleeve prints on both arms for all-around visual impact
Waffle-knit ribbed fabric construction for added texture and warmth
Crew neckline with a relaxed, oversized streetwear silhouette
Available in Black and Heather Grey colorways
Ribbed cuffs for a clean, structured finish at the wrists
Fit & Styling
The shirt is cut with an oversized, dropped-shoulder fit that sits comfortably loose across the chest and shoulders — ideal for layering over a longline tee or wearing solo with cargo pants, wide-leg jeans, or joggers. The extended sleeve length and relaxed body length make it a strong base layer for a grunge or dark streetwear look. Size M measures 67 cm in length with a 128 cm chest circumference; size up if you prefer an even more exaggerated oversized fit.
Product Details
Constructed from a cotton-polyester waffle-knit blend — approximately 60% Cotton, 40% Polyester — the fabric delivers a structured texture with moderate stretch and breathability. The distressed screen-print graphics are applied to the front chest panel and both sleeves. Crew neck. Long sleeves with ribbed cuffs. Machine wash cold recommended. Brand label: MT99.

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.
