This men's long sleeve button-up shirt delivers a smart faux two-piece look through a clever double-layer construction. The solid body — available in black or dark grey — is paired with a contrasting plaid collar and matching plaid inner lining that peeks out at the cuffs, creating the appearance of a layered outfit in a single, easy-to-wear piece. A small embroidered logo sits at the left chest, adding a subtle branded accent to the clean silhouette.
Product Highlights
Faux layered design: solid outer shell with plaid collar and cuff lining for an effortless styled look
Contrasting plaid fabric at collar and sleeve hem creates visual depth without extra bulk
Small embroidered logo at left chest for a refined streetwear detail
Full button-front placket with tonal buttons for a polished finish
Relaxed, slightly oversized silhouette suited to casual and smart-casual wear
Available in Black and Dark Grey, each with a grey-tone plaid contrast
Fit & Styling
The shirt is cut with a relaxed, slightly oversized fit that works well worn open over a tee or buttoned up on its own. The curved hem sits at the hip, making it easy to wear untucked. It pairs naturally with straight-leg trousers, chinos, or denim for a put-together casual look. The faux-layered collar detail means no extra shirt is needed to achieve a coordinated, styled appearance. Refer to the size chart: size M measures 71 cm in length, 112 cm chest, 48 cm shoulder width, and 60 cm sleeve length.

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.
