There is Tizz & Tonic where I (a cis male) bought a few boxers from which I really enjoy. Somehow there webshop is terrible, but this should be a good overview of what designs they currently offer: https://tizzandtonic.com/search?q=boxer&options[prefix]=last

Their design change regularly and be assured, when you take of your pants your boxers will get noticed and complimented :D

They are made in Portugal.
