Have a stinky friend, but don't want to hurt their feelings?
Then buy them this!
Japanese company Otoko Kaoru designed a shirt that releases "scent capsules" when it rubs against the skin and masks that nasty B.O.
The shirt goes for $35, but the so fresh so clean scent only lasts for 10 washes.
Or there's always the old fashion way of taking a shower and practicing good hygiene.
