i use a gc2b binder at school and i don't wear it for longer than the 8 hour school day. however, if i got a job that needed me to come in on school days, i'd have to bind for more than 8 hours. and if i got a job that involved physical work, i'd have to wear my binder during that physical activity. i have average size breasts, so something like the diy camisole binder doesn't help me. i also have two sports bras, but even when i wear both of them, or layer them on certain areas of my chest, i still have very obvious and lumpy boobs. aside from somehow finding a job with no physical activity that only needs me to come in on weekends, is there anything i can do so i don't have to wear a bra or bind unsafely at work ? if i wore a binder that was a size too big for me, would that make a difference in how long i could wear it ?
