As a guy, I didn't know it was "that bad" but I had some BO - when I was 16 or so, I had my first job in a grocery store. I went there after school without changing clothes. After a few weeks, the manager took me in the back room and gave me "that talk". it wasn't too bad at all - and I can see why. As a teen (this is in the early 80s) I didn't have a shower in our house, so I had to take baths and my mom never helped me much in the hygene department so I didn't buy my first deodorant until after "that talk".

I think it helped - sure I remember "that talk" but then it also helped me with a situation in life that needed attention. If you do it delicately, maybe you can show her you care without causing too much tension.

There is also the other end of the spectrum - too *much* perfume and body spray. Overwhelming perfume is just about as bad as horrible "jungle stink". Good hygene is learned, I think. Our parents should help us learn - but our good friends can help out too.
