Fit & Styling
This shirt is cut with an intentionally oversized, boxy fit — the dropped shoulders and generous chest measurement make it ideal for wearing untucked over slim trousers, straight-leg jeans, or layered open over a plain tee. The relaxed length sits at the hip, keeping proportions balanced. For a smart-casual look, pair with tapered chinos and clean sneakers. The navy version works well as a layering piece over a white tee, while the off-white reads lighter and pairs naturally with dark denim or cargo pants. Sizing runs true to the measurements provided; if you prefer a more fitted look, consider sizing down.
Product Details
Fabric composition: approximately 65% Cotton, 35% Polyester, giving the shirt a smooth, slightly structured drape with easy-care properties. Spread collar with solid contrast finish. Long sleeves with wide button cuffs. Full button-front closure. Single chest patch pocket. Pinstripe woven pattern. Available in sizes S through XL. Brand label: Changyou.

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.
