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 the flat-lay width instead 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.
