This men's long sleeve shirt delivers a sharp faux two-piece effect through a solid outer shell — available in black or white — paired with a contrasting pinstripe collar and matching cuffs. The deep V-neckline and layered placket create the illusion of a striped shirt worn beneath, making it a versatile high-street piece that reads as two garments in one.
Product Highlights
Faux layered design: solid body with contrast pinstripe collar and cuffs for a built-in layered look
Deep V-neckline with partial button placket on the black colorway
Long sleeves with wide, folded striped cuffs for a polished finish
Relaxed, oversized silhouette with dropped shoulders for a casual streetwear fit
Available in classic black and clean white, each with navy pinstripe contrast detailing
Spread collar sits open and relaxed, reinforcing the layered aesthetic
Fit & Styling
The shirt is cut in a loose, boxy silhouette that sits comfortably on the shoulders and through the body — ideal for those who prefer an oversized or relaxed fit. It works well tucked loosely into wide-leg trousers or worn untucked over slim chinos or dark denim. The contrast striped collar and cuffs add structure without requiring additional layering, making it an easy standalone piece for casual outings, street-style looks, or smart-casual settings. Refer to the size chart: S fits a 118 cm chest, M fits 122 cm, L fits 126 cm, and XL fits 130 cm.
Product Details
Shell fabric is a lightweight woven construction, estimated at 70% Cotton, 30% Polyester, giving the body a smooth, slightly crisp drape. The contrast collar and cuffs use a pinstripe woven fabric. Long sleeve length ranges from 59 cm (S) to 62 cm (XL). Garment length ranges from 66 cm (S) to 72 cm (XL). Shoulder width ranges from 51 cm (S) to 57 cm (XL). Available in sizes S through XL.

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.
