This white long-sleeve crew neck tee from BLACKE78 brings an American streetwear edge to everyday dressing. Bold black five-pointed star prints run down both sleeves, while the chest features a script "Racing" graphic, a chain-stitch "77" number, and an embroidered crest badge — all working together for a creative, INS-inspired look that reads effortlessly cool for spring and autumn wear.
Product Highlights
Allover black star prints along both sleeves for a striking visual impact
Relaxed raglan-style long sleeves with a clean crew neckline
Lightweight, smooth jersey fabric suited to transitional-season layering
Minimal plain back for a balanced, wearable silhouette
BLACKE78 woven label at inner neck; size L shown in detail shot
Fit & Styling
The tee is cut with a relaxed, slightly boxy fit — true to the oversized streetwear aesthetic. The raglan sleeve construction adds shoulder room without bulk. Pair it with slim or straight-leg trousers and sneakers for a clean street look, or layer under an open jacket for cooler days. The sizing runs generously: M measures 66 cm body length and 106 cm chest, L is 68 cm / 110 cm, and XL is 70 cm / 114 cm. Choose your usual size for an oversized feel or size down for a more fitted silhouette.

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.
