I just purchased my first bras, a couple cheap racerback sports bras, the plan is to use them to try to hide breast growth for a while, I've already got close to a B cup before HRT from being overweight probably. Anyway, the bras I got fit well, my back feels so much better with it on, but I noticed the straps can sometimes be visible through the neck hole of my shirt, and wondered if there's a certain type that'll be a bit more discreet but still compress well, these ones make me pretty flat, which is what I wanted, but still leaves me feeling a little deflated, no pun intended. Ideally the bra straps would fall further away from the neck, but still line up with a tank top (undershirt, obviously not expecting a tank to hide a bra) for plausible deniability!
