When take a photo like that the pinstripe just looks immaculate, but in a conservative environment/office I rarely see anyone wear the pinstripe anymore. But of course a moderate lapels would be best to even out the proportion.
If you happen to be a beefy 6 feet tall guy, wearing a slim fit suit just makes you look silly. The point is, wear a suit that fits your body type and not get all caught up with the trends. Slim fit suits are not for everyone.
