I didn't realize how dainty my wrists really were until I got my Apple Watch today. I'm a 6' tall male, and I can go all the way up to the last hole but it's just the slightest bit tight. The second to last hole is too lose, but I'll probably end up using that second to last hole. I expected the 42 to be bigger and this doesn't seem overly large. But I have to say, this has me thinking that maybe I should have gotten the 38 instead.
