Anyone up for a challenge? Personal Trainer Caps?

My wife works out two mornings per week with a very impressive black PT twice a week. His gym is private, one customer at a time. She continues to be self-conscious about how her nipples look in her workout attire, ... but keeps wearing them. She tells me that to her this is just a workout, hard work and not sexual in any way. But it's pretty exciting to me.. even if nothing is happening.
Any of you caption geniuses have any ideas/pics for caps along this theme?
Thanks!

Well, then anyone know where I can find pics or caps like this?
Thanks!
