I'm having a custom suit made. One choice I never thought about was the rear pocket closure. 1) No button 2) Button through a button hole 3) Button with a tab closure (not sure formal name) Which should I use? Same for both pockets? I should note that I NEVER put anything in the back pockets of a pair of pants. Because of this, my inclination was to avoid buttons entirely to keep a sleeker look. Any and all thoughts are appreciated.
