How do you tell someone nicely that he or she stinks?

By telling a joke. Then that friend of yours could realize that isn't that fun and definitely will take his appeal more seriously and will not allow a bad smell anymore.

Hi, I had a vietnamese friend who were once from refugees camp, and later with the help of rich aunt here in manila manage to have a passport and capital and was new in business world. That was years back when I was staying in Ilo-ilo City. This vietnamese not only had underarm odor, but also bad breath and she loves to wear sleeve less blouse with underarm hair.She can't relate people in English too as she speaks vietnamese language only. The people and friends don't like to mingle with her or deal with her for the reason above mentioned. I was really feeling sorry for her and I just could'nt explain to her why those people run as far when she comes. Because she was really totally alone and has no friends, I befriended her and she was so happy that she comes to me very early in the morning to wake me and and chat with me before she will go to her jewelry store and me to mine. Every time she comes and wake me up, I would cover my mouth and never speak to her instead showed her that I will first brush and wash my face before I would do the talking.At night time she would again drop by as we have to talk business, and I make it a habbit to clean myself infront of her, like taking out my underarms hair, do the body cleaning, apply sweet scented cologne even if I am bout to sleep. One day together We travelled to Manila to buy things and we happened to check in together in a hotel, which gave me really the chance to really show to her the grooming I am making to myself, and I happened to tell her story how filipino man love and attracted to well groom women.(She had a crush with my male friend that time) From then on, I have seen different person. Later when we were back to Ilo-ilo, I noticed she has no hair in her underarm, and she no longer stinks, and best of all no more bad breath, because I taught her how to prevent bad breath. Haha, would you believe she is now having a big company here in manila and very sexy still with so pleasing personality. I am very happy for her.

I've been in this situation before. Luckily, he is really my close friend that's why he trust me. First, I gave him a set of powder, deodorant and cologne so my real intention wouldn't be so obvious then I told him directly that he doesn't smell so good lately and a nice bath with calamansi will do him good. It is better for him to hear it from me than hear it as a hearsay from other people. If a person who stinks isn't your friend nor someone you know, it is better to keep mum about it and try to avoid them as possible. Spraying a cologne all over will also lessen the odor.

very simple dear friend . just buy one good quality deodorant and gift it away soon at the earliest opportunity!! try and see the results!!

Buy them a bath set and maybe perfume or cologne. Then recommend they use them. I don't know if they will overlook it but its worth a try.

I don't think there is a nice way to say it. I have a friend who smells really bad and one time I didn't realize it was him. We were sitting in my car and with two other people and I said "Whoa, what is that smell?" When I realized what it was I felt so bad but I have yet to figure out a way to mention that deodorant is a good thing, as are baths and showers...Eww...
