Sizes, ethics and print
All sizes have a generous fit.
Most clothing is American Apparel, which was recognised by PETA as best vegan-friendly clothing company (https://www.americanapparel.net/presscenter/awards.html). All other clothing is very similar in size and fitting to American Apparel products. The prints are made in Britain by a print company in London, UK.
If you prefer a snug/slim fit I would recommend a size lower.
To give you an example, I am 6'1, 82kg and athletic and M fits me well, a S would be very slim fit for me.
I recommend for female t-shirts to pick a size one below your usual to ensure a proper fit.
For unisex clothing I recommend girls to choose two sizes below your usual fit and for guys your usual size or one size below for a snug/slim fit (see above male sizes).
