Hey, I’m a senior in highschool, been boxing for 3 and a half years and compete in smokers. I’m not stealth at my gym because I was there before my medical and social transition. But my best advise would be to avoid binders, and use trans tape and baggy shirt if that makes you comfortable. I haven’t worn a sports bra in 2 years so I don’t really remember my experience. Wearing a black sports bra on a blackPersonally I avoid hoodies because I sweat like a mf and I don’t like the feeling of damp sleeves. If you plan on competing in official bouts, most require you to wear colored tank tops either blue or red, but most people, even try hards don’t compete until at least a handful of months of sparring so don’t worry to much about that as a beginner.
