Fit & Styling
Cut in a slim, fitted silhouette, this top is designed to sit close to the body without feeling tight. It works well tucked into chinos or slim trousers for a smart-casual look, or worn untucked over joggers for a relaxed off-duty outfit. The stand collar adds a subtle elevated detail that makes it easy to wear without a jacket. Refer to the size chart: size M measures 64 cm in length, 96 cm chest, 47 cm shoulder width, and 57 cm sleeve length, scaling up consistently through XXL.
Product Details
Fabric composition is approximately 60% Cotton, 35% Polyester, 5% Viscose — a blended knit construction consistent with the fine-gauge heathered texture visible in the product images. The stand collar and button placket are neatly finished. Machine wash cold; lay flat to dry is recommended for this knit construction. Available in sizes M through XXL.

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.
