Luckily, most people here seem to understand that coaches most likely do this to not just talk to one or two girls and tell those 'They smell bad', cause that might make those girls feel really uncomfortable. Someone once told me when I was young and I remember that for years, as soon as I had sweat, I would try to keep my arms down... My friend works as a coach for girls on the highest levels and because of all the funds we have here, even children that come from a less fortunate family can train. Last time I visited, they had a girl training about 16 hours a week, who only had 3 leotards. For a long time it wasn't really an issue, but by that time it started to be, since she started to 'smell' a bit more. My friend asked for advice, since the coaches felt like they should not say 'buy another leo' or 'you smell', but they did want to address the problem. I offered to buy her one or two leos, but we ended up having a conversation about leotards with all the girls at the end of the lesson and the girl told the other girls that her mom tried to wash them after each practice, but 'they don't always dry in time'. We did not once mention that she smelled bad or anything, nor that I was about to buy her more leos, conversation just popped up because of a new leo someone was wearing. After the girl told her story, one of the older girls ran off and asked her mom if she could give some of the leotards she didn't fit anymore. Problem solved, but I still remember her coaches feeling bad since they did want to address the issue, but didn't know how to without offending anyone.
