GET THE PERFECT FIT

How to Measure

Measuring yourself is proper easy and helps you avoid that 'baggy duck' or 'squeezed duck' look. Grab a flexible tape measure and follow these three simple steps.

  • Chest: Wrap the tape measure under your armpits around the fullest part of your chest. Keep it level and don't hold your breath!
  • Length: Measure from the highest point of your shoulder down to where you want the hem to sit (usually just below the hip).
  • Sleeve: Start from the center back of your neck, across the shoulder, and down to the wrist bone.

Fit Guide

Regular Fit

Our regular fit follows the classic silhouette. It's not too tight and not too loose, sitting just right for everyday wear. Choose this if you prefer a standard, timeless look that moves with you.

Oversized Fit

The oversized fit is all about that relaxed, drop-shoulder vibe. It features extra room in the body and sleeves for a contemporary, street-inspired aesthetic. Best for lounging or styling up a loose, layered outfit.

READY TO GET PROPER DUCKED?

Now that you've got your numbers sorted, there's no excuse for lookin' a bit daft. Pick your size with confidence and grab some proper clobber.
