What is the largest gummy bear implant size that can go through the underarm? (Photos)

Hi! 1) I’m interested in a modest augmentation with, if well-advised, textured tear-drop implants. I am really proud of my small areolas and I don’t think the final result I desire will hide an under-breast scar that well. I just want bigger but not a size that was .1% of the population before aesthetic surgery was invented. 2) Also my momma had big Texas implants done on her completely flat chest when she was 18 around 1984. The only time I’ve ever seen them, her areolas looked like popped out disks and they were much larger than mine are at 37 and she was around the same age. She breastfed me for 6 months and my sister that’s only 15 months younger for about 2. I’m nuliparous though I did have a terminated pregnancy that went to 14 weeks, if that matters. What was/is going on with her areolas? Thanks!!!
