Hi all !  I'm new to the forum, my name is Martin, 42 years old, I'm a baker in France. 
Yesterday I received my first IH jeans, an 888 25oz, what a monster! 
I am 1.73m ( 5'8 ) tall and I weigh 72kg (159lbs), after a long hesitation I chose a size 31. I manage to close the button quite easily but I find the waist tight.  On the other hand, I am comfortable in the butt and thighs. 
What do you think, should I change it to a size 32?

I realize that I did not write in the right place, here it is the topic of 666, sorry! 
Anyway, thank you for your opinion
