But the sad part is that, there is absolutely no polite way of telling them that they smell.
One could always wait for their birthdays and gift a perfume or a deodorant, but then that leads to an awkward situation where the receiver tries to decipher the "thought" behind the gift.
The only solution is to gift a deodorant anonymously; a deodorant that actually works for those unfortunate people who stink abnormally.
Deodorgrams is one such service (gifting program) that only sells natural deodorants with the benefits of letting you anonymously gift a deodorant to your stinky loved ones. They call is the 'extra -odor-nary' solution.
More than the product, I think it is the concept of gifting a deodorant anonymously that could potentially make Deodorgrams a success. They even have creative templates for messages that could be included in the gift:
Message A: "You've always been such a cute little stinker, now you can just be cute and little! Please enjoy this hard working natural deodorant sent to you from a caring friend."
Message B: "For Pits Sake! Throw out your current deodorant and give this one a try. You deserve a natural deodorant that works!"
Message C: "There''s no need to sweat it, but if you do, try this natural deodorant that works!"It's not necessary that you gift this to someone anonymously, you can always dare to have you name included if you like. However, if you think telling people that they stink anonymously is still a better idea, then head over to their website, where all you need to do is fill out the recipient's address, when he/she receives it, the the return address will be of the company.
