Please measure yourself and use these charts to choose the right size. 

These measurements are for a standard comfortable fit, if you would like a looser fit please choose one size up from our recommendations.


Use a flexible tape measure or a piece of string and a ruler. For the best fit, measure over undergarments that you plan to wear with your clothing. 

A: Chest

Lift your arms up and wrap a flexible tape measure around the highest part of your chest and shoulder blades. Drop arms to your sides (over the tape) to take the measurement. It should be under your arms. 

Shirtbox chest measurements are all the way around your body, not just across the front of your chest. 

B: Body Length

Use a flexible tape to measure from the top of the shoulder down your body to the point where you want your garment to end.   



Have no fear, you can return your product within 30 days for a refund or exchange.

Quality t shirts

Cannot fault service - quality and wearability

Stuart H. (Sydney, AU)
Who'd da thunk?

As a paraplegic, tee shirts are great and easy to wear. I bought one as a trial, to check out the quality etc. Who'd da thunk purchasing a "T" from a pommie outfit would be a good thing, BUT yes, it is! Pleased with it at this end and would recommend it to anyone and everybody.


Patricia W. (Fareham, GB)

My grandson thought his shirt was most appropriate and so did his parents. What is more he liked it so much but he will actually wear it!.

David S. (Winsford, GB)

David W. (Bournemouth, GB)
No I am right?
