I know this isn't the place for me but I really do want your help, if any problems with me posting I will take down the post. So basically I just got her a set of breast forms (that she helped pick out) but she's very shy and don't want to post much so I do as I want to help her, basically I've searched the entire internet on proper placement for them on the chest but so far I haven't found anything :( So I'm asking here what placement(s) would/could work

(If needed she's pretty tall and fairly slender, so no wide shoulders or ribcage, idk if that would be important for the placement)

She still haven't tried them on (outside of in bra pockets, so far it hasn't been a problem but they also work with adhesive and I know she would want to try that too some time)

Also is there anything else I should keep in mind as she tries them on and gets more comfortable with them, basically how can I be as supportive as possible?
