Binding safely

Im fairly new to binding. ive just actually started to accept myself and i was wondering if i could bind with two sport bras? im not self sufficient enough to risk getting a binder (transphobic parents)

i want to be safe despite my STRONG desire to go crazy and make sure it isnt visible from any side.

if not, any other advice i really want to just see the tatas go in my masc outfits.
