My boyfriend needed a suit, he is 1,85, BMI 22,8, I'd say he has a quite slim built, no naturally broad shoulders, but because he goes to the gym regularly he has put on some muscle mass. He's by no means skinny. No chance of him fitting into a slim suit, we had to go for the skinny and super skinny ones... His hips seem to be a bit wider, so no problem with pants. However, that's my problem, I don't have womanly hips and need a 24 when skinny and a 25 when slim - many brands don't even make these sizes.
