Here's what I can offer to the conversation. My wife is 5'1" / 1.55M and has 1200cc implants, and we have a son who is now almost 16. She got her 1st implants several months after he was born, 475ccs. Was happy to show them off as much as possible, but was actually disappointed by how easy they were to hide. So easy to be discrete.
A year and change later she upgraded to 800ccs. Not as big as we had hoped for, but pretty nice. In a tight and/or low-cut outfit she had obvious big fake tits. When she wore something loose or puffy, they were still easy to hide. She had those implants for 14 years. There were definitely some times when our son was in grade school when she would something that didn't hide them and other moms would talk shit, but that didn't happen often. Nobody's every given her a hard time, and it wouldn't matter if anybody had - they were a great boost to her self confidence and she's loved having boobs!
Ash forward to about a year-and-a-half ago, and she upgraded to 1200ccs... and immediately wished she had gone larger! Our son was in middle scchool then, high school now. Much less interaction with other moms, so nobody talks shit like the elementary school moms did. She can still hide them, especially in winter with a big coat, but, generally speaking, it's pretty obvious she has big fake tits. She LOVES them!!!! A lot of people, family members included, didn't even notice her upgrade and she didn't tell them. They remembered she had big fake tits, so just thought they were always this big. One oerson asked and wife said she had just bought a new push-up bra 😉
Planning to upgrade again next year to 2000cc+...... will be a new experience that we are both looking forward to! 😁😁😁👍
Hope this helps!
