I purchased the N&F WG in size 31, I usually wear 32 in denim. Received them today and tried them on, my research here has led to me think that the top button should be very hard to button. On these I not only got the top button but if I pull a little bit, I can fit my open hand down till a little past the knuckles. Should I return them for a 30 or pre-soak and where till they stretch out? I am going to a slim but not skinny look but I am not very well verse in raw denim.
