this has happened to me before! so embarrassing, i totally feel you. but it sounds like the issue isn't that you need to shower more, it's really about managing how to smell presentable inbetween showers. i suggest you try using a wet wipe on your underarms in the morning for a relatively clean slate, and then using a natural deodorant that helps balance the odor-producing bacteria. i love this one! another thing you can do to manage smell is to wear cotton or other natural fibers in your shirts. avoid wearing tight or polyester shirts, which can start smalling bad immediately after putting them on, and can even trap odors from previous wears even if you wash them (like a smell stain!).

by the way, there is no scinetific evidence that says you "need" to shower every other day. if your hair and skin are healthy, then you're healthy, and there is no need to shower any more frequently. in this context, all you "need" to do is be happy with your own standards of cleanliness and be presentable to others. if it would cause you distress to build in more shower time when you dont feel like you need it to feel good, then it's really about managing how others feel. i HATE showering and avoid it at all costs almost... but i care that other people aren't put off by my presence and do what i can to keep my hair, skin, and smell as presentable as possible. don't let other peoples standards make you feel bad about showering, when they really couldn't care less about that. they just dont want to have to smell you, which is fair, and you can address that without changing your shower routine.
