ADULTS

Author t-shirts are cut by hand and sewn in small batches in Kolkata, India by our friends at Freeset Global.
While there may be slight measurement variances between shirts, finished shirts are tested to ensure any differences are minor and will not affect fit.
Not sure what size to order?
Simply find one of your child’s favourite shirts and compare its measurements with our size chart. We think this method is a more accurate indicator of fit.
Measuring for comparison 
Lay the chosen shirt on a flat surface, smooth out any wrinkles.
Chest
Measure across chest from side seam to side seam just below the armpit.
Length
Measure from the point where the shoulder seam meets the neckline ribbing, straight down to the bottom of the shirt.
Shrinkage
A new shirt can be expected to experience 3% shrinkage after normal washing and drying.
Wear + Care
To help your clothes (and our planet) enjoy a longer, better life, we recommend washing printed and dark items in cold water, hanging to dry or drying on a cool setting.
