not sure how tall you are or what type of environment you need to wear the suit, but anything business i would stay with the two button. going out i may consider other styles. i wear a 52. Ralph Lauren, Sean john is what i have mostly, but to get these tailored with the shape we have cost a ton. i can get a better fit going to a big and small man shop. at a traditional store a 52 suit comes with a 48-50 inch waist and with one suit my front pockets were in the rear they had to take it in so much. and the length between the crouch and the top of the pants is long.....the crouch was damn near to my knees.
also, if there is a Mens warehouse in your area, compare prices and shop around. I didn't find anything under $700 for what i liked....but found better deals at the outlet malls.
