Life is good has many styles of shirts. This website is similar to the Life is good website: the individual size measurements, or range of size measurements for each individual style is not listed.
However, for your convenience, we have posted the 'classic' shirt size measurement information previously provided from Life is good -- here, in our size charts page.
We have also included a brief explanation of our feelings of the various styles as to which is more of a relaxed fit or slim fit.
