FWIW, I also took one size down (32, being 33 in trousers). When going 2 sizes down in the slim fits, while I could button them, the upper block was just too tight in the thighs and crotch, like I was wearing women's jeans. I thought the waist had a good amount of snugness, and with some nominal stretching from wear, would fit best after several wears. I was not confident the other areas would likewise stretch. I work out regularly with decent size legs if that helps.
