CARE TIPS

CARE TIPS

Made from 100% cotton, Callo Denim

First wash = just denim & you

Raw cotton denim can release excess dye at first. Wash it alone or with dark tones to keep your Callo Pants looking fresh.

Cold & gentle is the way

A delicate cycle in cold water protects the fibers, preserves the fit, and keeps that just-made feel.

Skip softener the first time

Let the fabric breathe naturally. Softeners can trap residues from the making process.

Inside out, always

It's the easiest way to reduce fading and protect the surface from unnecessary wear.

No heat on embroidery

High heat can weaken and unravel the stitching. Treat the embroidered details like the art they are.

Size exchange & returns

Each piece is made in small runs. We accept size exchanges within 14 days of delivery. Original item must be unworn and in original condition
