Can wearing a bra to increase bust size really make a difference? - #22139

I am trying to figure out if a bra to increase bust size actually works, you know? Like, I mean, I’ve always been kinda self-conscious about my smaller breasts, and I saw these ads about bras that claim they actually help with this. I saw a friend wear one and she looked way different, but is it just the bra or real increase? I’m wondering if it's just about how they fit or designed or something. Also, I’ve read how some women say they feel more confident and think it does work like a miracle, but then, others say it doesn't help at all! Is it possible that a bra to increase bust size can actually work over time or is it purely psychological? Got a friend who's been wearing one for months, but she doesn't really say she's noticed a big change. So, like, is it worth investing in these types of bras or do they just not cut it? I really want to understand if there's a real difference or if it's just marketing hype. Any experiences would be really helpful!
