This blue white striped shirt brings a playful coastal energy to your wardrobe through richly detailed embroidery across the entire front panel. Featuring a contrasting denim collar, long sleeves with buttoned cuffs, and a relaxed oversized silhouette, it blends streetwear attitude with a vacation-ready aesthetic that works from spring through autumn.
Product Highlights
All-over front embroidery featuring palm trees, starfish, a lighthouse, surfboards, seashells, and tropical text motifs
Contrast denim point collar adds a bold color-blocking detail against the light blue stripe base
Vertical blue and white stripe fabric with a clean, unembellished back panel
Button-front placket with decorative brown buttons running from collar to hem
Relaxed oversized fit with a slightly curved hem for a casual, streetwear-influenced silhouette

Pair with straight-leg jeans or chino shorts to let the embroidery take center stage. The denim collar naturally coordinates with denim bottoms for a tonal look. Sizing runs relaxed — refer to the size chart and size down if you prefer a more fitted appearance.

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.
