My tennis lessons are usually long so I end up wearing my thicker diaper for class. This hot day, I also ended up wearing only my small tennis skirt which didn't really cover my diaper all of the way. As my diaper got fuller, it kept sagging below my skirt hem. The instructor asked my boyfriend what I was wearing at one point at the end of class. He just answered, "A diaper". I was so embarrassed, but I guess I don't have to try and hide my diapers from my tennis coach anymore.
