This men's long sleeve rugby polo shirt combines a classic sport-inspired silhouette with bold streetwear details. Built in a relaxed, oversized fit, it features a black base with a wide royal blue chest stripe, a contrast cream polo collar, and a lace-up tie at the neckline. A large "52" number graphic sits on the upper chest alongside an embroidered crown badge, while a flowing script logo runs across the blue panel — giving the piece a retro athletic character that works equally well as casual outerwear or a statement layering piece.
Product Highlights
Relaxed oversized fit with dropped shoulders for a comfortable, streetwear-ready silhouette
Bold black and royal blue colorblock design with a wide horizontal chest stripe
Lace-up tie closure at the neckline for an adjustable, vintage rugby-shirt aesthetic
Contrast cream polo collar adds a clean, preppy contrast to the dark body
Embroidered crown badge and large "52" number print on the front chest panel
Ribbed cuffs on long sleeves for a neat, secure finish at the wrist
Fit & Styling
This shirt is cut in a loose, boxy fit that sits comfortably on the body without being shapeless. The relaxed shoulder and generous chest measurement make it ideal for layering over a plain tee or wearing on its own. Pair it with slim-fit jeans or tapered trousers to balance the volume, or lean into the sporty aesthetic with wide-leg cargo pants. The cream collar and lace-up detail make it versatile enough for casual outings, weekend wear, or a retro-sport inspired look. Refer to the size chart: S fits a 112 cm chest, M fits 116 cm, L fits 120 cm, and XL fits 124 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.
