Comfortable, minor sizing issue

I ordered a few pairs of the heren boxershorts and a ronde hals t-shirt. The Mellowood fabric really is soft, much better than my old cotton ones. Delivery took about 5 days to reach me, which was fine. The t-shirt fit perfectly, but the boxers felt a bit snug for a Large, so I'd maybe size up next time. Prices are a bit higher, but for the quality and sustainability, I think it's fair. Overall a good experience, I'll probably order again.

Mine took about a week and a half to New York. Not super speedy but not bad for international.

Yeah, I think it was maybe 7-10 days for me in Cali. Came in a pretty small package too.

are undiemeister's sizes pretty standard? like, if I'm usually a large in other brands, will that work for their boxers or should I go up/down?

I found them true to size. Stick with your usual. They're a bit snug at first but stretch a little with wear.

Mine fit perfectly! I usually wear a medium and ordered a medium, no issues. Plus, the fabric is super soft, you'll love it.
