The short answer is “a lot”
None of the above were cheap…. (I’m “mature” enough not to do “cheap” anymore!!) So when I wear my Amoena’s’ I love how soft they feel in my bra. As the post above states, sadly they wont stay on bra less. But in the morning when I take off my bra and have them “hanging loose” with that “overall stick”, it’s the closest I’ll even get to having “real breasts”.
