A few ideas I would love to see pondered are a dress tie that you can combine to the suit jacket or any top that makes sense to complete the Business ensemble. You can also use the tie as a bandana to "rambow" yourself up, as a bandage, or to gag someone. I would love to see a hidden item slot where you can combine a small fire arm or knife with tape to then strap to your leg. In most stick up situations people tell you to drop your stuff and lay down and I think if this idea were implemented, then you could possibly get away from a sticky situation by pulling out your sneaky weapon before they realize it. Ripping the sleeves off of long sleeve tops to then become rags could be strategically helpful. Honey could be used as an antiseptic in case you use dirty rags to bandage with a chance at killing the infection.
