A relaxed, oversized plaid shirt built for effortless everyday wear. Featuring a classic grid check pattern, a point collar, and a single chest pocket with script embroidery, this long-sleeve button-up shirt blends Japanese casual sensibility with a streetwear-influenced silhouette. Available in a muted beige-blue plaid and a bold orange plaid, it transitions easily from layered looks to standalone warm-weather styling.
Product Highlights
Oversized relaxed fit with a dropped shoulder and boxy silhouette
Script "Aasta" embroidery on the chest pocket and back yoke
Classic point collar with a full button-front placket
Single chest patch pocket for a utilitarian detail
Available in two colorways: soft beige-blue plaid and vibrant orange plaid
Long sleeves with buttoned cuffs for a clean, polished finish
Fit & Styling
This shirt is cut with an intentionally oversized, boxy fit — ideal for wearing untucked over wide-leg trousers, cargo pants, or relaxed denim. The generous chest measurement (120–128 cm across sizes M–XL) makes it suitable for layering over a lightweight tee or wearing open as a casual overshirt. The beige-blue plaid reads as a versatile neutral, while the orange plaid makes a bolder seasonal statement. Refer to the size chart: M fits a 120 cm chest, L fits 124 cm, and XL fits 128 cm.
Product Details
Fabric composition is approximately 100% cotton woven fabric, giving the shirt a soft hand feel and natural breathability suited to spring and autumn wear. The check pattern is woven into the fabric rather than printed, providing consistent texture across the garment. Shirt length ranges from 72 cm (M) to 76 cm (XL), with shoulder widths from 54 cm to 58 cm and sleeve lengths from 56 cm to 58 cm.

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.
