This oversized denim shirt jacket brings a bold American collegiate aesthetic to your wardrobe. Featuring a large arched "Boston Athletics 97 Massachusetts USA" graphic across the chest, a sun-faded gradient wash, and a relaxed boxy silhouette, it sits at the intersection of vintage streetwear and campus style. The button-front closure, point collar, and ribbed cuffs give it the structure of a shirt while the heavyweight denim fabric and oversized cut make it wearable as a light outer layer.
Product Highlights
Bold "Boston Athletics 97" collegiate crest graphic printed across the front chest
Vintage sun-bleached gradient wash — darker teal at the sleeves and hem, faded sandy tone at the center
Oversized, boxy fit designed to be worn open as a jacket or buttoned as a shirt
Point collar with branded interior label and antique copper-tone snap buttons
Ribbed elasticated cuffs for a clean finish and comfortable fit
Plain back panel with a subtle two-tone wash effect for a clean, versatile reverse
Fit & Styling
Cut with a relaxed, oversized silhouette that sits comfortably on the shoulders and through the body. The dropped shoulder and wide chest make it ideal for layering over a graphic tee or hoodie. Pair with straight-leg or wide-leg jeans and chunky sneakers for a full retro-American look, or wear open over a white tee for an effortless campus-inspired outfit. The size chart below reflects actual garment measurements — if you prefer a more fitted look, consider sizing down one size.

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.
