^Judging by the way the pics appear on my computer screen, there don't seem to me to be any egregious fit issues that would indicate that the tuxedo is too large for you. The shirt, however, looks too large for you, and the shirtsleeves seem to me to be too long. Is this the shirt you plan to wear with it?
When you have the pants altered, you may want to have the single vent in the jacket closed. Center vents in tuxedo jackets really upset tuxedo "traditionalists"!
