try to wear:
double-breasted dark jacket in subtle chalk stripe with the hard-shoulder, draped chest and a soft waist.
a pair of pants to the jacket. they should be loose in the hips and not very much taper to the ankle (I think 20-20,5 cm width at the bottom). pants should be cuffed with a width of 5 cm.
pants must be fully supported by suspenders.
shoes with rounded toe. color black or espresso.
shirt, tie and handkerchief you will pick yourself. I'm sure of it.
I'm sure this option will be very good for your physique. Good luck!
Great advice, where people have been telling him to taper his pants. They need to be loose not to emphasize his hips
