Sizing Guide

At Core Tees, most of our adult tees are 100% cotton. Exceptions include some Heather colours, which are a blend of cotton and polyester, and other blended fabrics as noted in the product description. Please check the description before purchasing, and if you have further concerns please contact us.
Cotton and other fabrics can stretch and shrink, but most materials are 'pre-shrunk' before manufacturing, reducing the chance of shrinking after purchase.
We source products from a range of manufacturers so there may be small variations in the sizing of your delivered product.
Where mentioned, Relaxed Fit describes a tee with a traditional square cut along the sides, while a Slim Fit tee has been tailored to pull in at the sides for a closer fit.

Please see our Returns Policy if you wish to return a product that you are unhappy with.

Unless otherwise stated in the product description, all of our products are labelled and sold as US sizing.
Please check your sizing on the below charts to reduce the delay and cost in returning for the correct size.
As a guide, we have converted the US sizing to approximate Australian sizing and centimetre measurements.

US Mens Sizing: Measure around the chest underneath your armpits to get your size.
Alternatively you can measure the width of your favourite tee between the armpits and double this number.
The AU size is an approximate conversion based on department store sizing.
