A relaxed-fit Harrington-style jacket built around a bold American collegiate aesthetic. The TP516 features a stand-and-turn collar, a full zip-and-snap placket, dual chest flap pockets, and a gold embroidered crest badge on the left chest — all finished with an elasticated hem and cuffs for a clean, cropped silhouette. Available in khaki and navy, it pairs effortlessly with wide-leg trousers or cargo pants for a streetwear-ready look.
Product Highlights
Gold embroidered crest badge on the left chest for a vintage American collegiate feel
Stand-and-turn collar with full-length zip and snap-button placket
Dual chest flap pockets plus side hand pockets for functional storage
Elasticated ribbed hem and cuffs for a structured, cropped finish
Lightweight 100% polyester shell and lining — easy to layer over hoodies or knitwear
Oversized boxy cut designed to be worn relaxed through the shoulders and chest
Fit & Styling
This jacket is cut with a deliberately oversized, boxy silhouette — the chest measurement runs wide (135–147 cm across sizes S–XL) and the body length is cropped at 66–72 cm, making it ideal for layering over bulkier pieces. The model is shown wearing the navy version with black wide-leg pants and pointed boots, demonstrating how the cropped length balances a voluminous lower half. For a cleaner look, pair the khaki version with straight-leg chinos or dark denim. Refer to the size chart: S fits height 155–165 cm / 80–110 jin; M fits 165–170 cm / 90–120 jin; L fits 170–175 cm / 100–130 jin; XL fits 175–185 cm / 120–150 jin.

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.
