A relaxed, oversized crewneck sweater built for streetwear-leaning wardrobes. Constructed in a textured waffle knit and finished with an acid-wash treatment, this piece carries a worn-in, vintage aesthetic straight out of the box. Graphic lettering across the chest and intentional distressed hem detailing give it an American street-influenced edge that pairs naturally with wide-leg denim or cargo pants.
Product Highlights
Waffle-knit construction with an all-over textured grid pattern for visual depth and warmth
Acid-washed finish creates a faded, vintage look across both colorways
Embroidered-style graphic lettering on the chest: "happy every day / thebangouluo / Don't be unhappy"
Intentionally distressed hem with dropped loops for a raw, deconstructed streetwear detail
Ribbed crew neckline, cuffs, and waistband for a clean finish against the relaxed body
Available in washed blue and washed black
Fit & Styling
The silhouette is oversized and boxy, sitting comfortably below the hip. It is designed to be worn as a standalone layer over a basic tee or long-sleeve shirt. The dropped shoulders and wide chest make it ideal for a relaxed, layered streetwear look. Refer to the size chart for chest and length measurements and size up if you prefer a more exaggerated oversized fit. The washed black colorway reads darker and more subdued; the washed blue offers a lighter, denim-adjacent tone.
Product Details
Material: 80% Acrylic, 20% Cotton waffle-knit fabric with acid-wash treatment. Crewneck silhouette with ribbed collar, cuffs, and hem. Distressed raw-edge detailing along the bottom hem. Graphic lettering on front chest. Available in sizes S–XL. Measurements are taken flat; a tolerance of 1–3 cm is within normal range.

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.
