A relaxed oversized plaid button-up shirt built for everyday street style. Crafted in a classic multi-tone check fabric, this long-sleeve shirt features bold white embroidered Pegasus motifs on both chest panels, flanked by red star accents, with script lettering reading "Madegpsr Sportclub" — giving it a retro American varsity character with a Japanese streetwear edge. Available in dark olive-black plaid and khaki plaid colorways.
Product Highlights
Dual embroidered Pegasus with wings on the chest — a standout graphic detail in white thread
Red star embroidery accents above each Pegasus motif for a bold, retro aesthetic
Classic plaid woven fabric in two versatile colorways: dark olive-black and khaki
Oversized relaxed silhouette with a curved hem and back box pleat for ease of movement
Button-through front placket with tonal snap-style buttons and buttoned cuffs
Point collar and clean back yoke construction for a structured casual look
Fit & Styling
This shirt is cut with an intentionally oversized, boxy fit — ideal for wearing open as a layering piece over a plain tee, or buttoned up as a standalone top. The generous chest and shoulder measurements make it a true relaxed-fit shirt rather than a slim cut. Pair it with straight-leg trousers, cargo pants, or denim for an effortless American casual or Japanese streetwear look. The dark olive-black plaid works well for autumn and winter layering, while the khaki plaid suits spring and transitional seasons. Sizing runs large — refer to the size chart and consider your preferred fit when choosing.
Product Details
Material: approximately 100% polyester woven fabric with a soft hand feel, constructed to replicate the texture of a traditional plaid flannel shirt. Long sleeves with single-button cuffs. Curved shirttail hem. Back yoke with center pleat. Available in sizes M through XXL.

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.
