The Seakoff Layered Knit Check Shirt delivers the visual depth of a layered outfit in a single, easy-to-wear piece. A textured heather-knit body sits over a contrast plaid underlayer, with the check fabric peeking through at the collar, sleeve cuffs, and hem. The result is a polished yet relaxed silhouette that reads smart casual without any extra effort.
Crafted in 100% Cotton
Made entirely from cotton, this grey button up shirt offers a soft, breathable feel suited to everyday wear. The textured knit surface adds visual interest and a tactile quality that sets it apart from standard button-up shirts. The structured silhouette keeps the fit composed while the short sleeves and relaxed chest allow comfortable movement throughout the day.
Versatile Smart Casual Style
Available in light grey and dark charcoal colorways, this shirt pairs effortlessly with chinos, straight-leg trousers, or dark denim. The button-up front closure and point collar give it enough structure for a smart casual setting, while the streetwear-inspired layered detail keeps the look contemporary and relaxed. A wardrobe-ready piece that transitions easily from daytime errands to casual evenings out.

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.
