Size Guide
Pi Clothings uses a slim fit cut across all t-shirts and sleeveless tees. If you’re between sizes or prefer a relaxed feel, go one size up. Boardshorts are sized by waist in inches — true to size.
How to Measure Yourself
Measure around the fullest part of your chest, keeping the tape horizontal.
Measure from the edge of one shoulder seam to the other across the back.
Measure from the highest point of the shoulder down to the hem.
Measure around your natural waist, just above the hip bone. Keep one finger under the tape for comfort.
