The really pointy ones were sort of an exaggerated advertising thing. Young women had selections of bras that weren’t pointy. Not much in the way of photographic evidence remains of this unless you look at youthful pictures of your mom or grand mom. A pointy bra in my day was sort of slutty.
Secondly, fabric has changed a lot since the fifties. It’s been decades since I’ve seen a cotton bra, much less worn one. And I think you really need that cotton with the concentric circles to give you the rocket nose look.
