I agree with Lynne and jodevizes! I am a 34B and although I'll admit there have been occasions where I'd have liked a bit more volume (so to speak), I LOVE the size that I am (especially the older I get). There are definitely times in my life where I'd prefer not to have large breasts and would feel conspicuous with them (i.e. work, family functions, in everyday life where I want to wear a tank top without being "poppin' fresh"). I also feel a B cup is exactly the right amount for me to be able to "work with" if I want to be a tad sexier for a night out or whatever occasion.
My best friend, who was also a 34B, got implants and is now nearly a D. She has a broader frame than me, so they look pretty natural, not out of place. She's now very happy with them and had wanted them for a very long time.
But I dearly wish that more people would find what they DO like about their bodies and not let Victoria's Secret, Hollywood, or a bully, tell us what our most important feature is. I know few - if any - people consciously allow that to happen, but it's like osmosis. To me it seems like letting them win.
If you do get them, one interesting word of advice my friend's doctor gave was that saline will sometimes slosh audibly, especially in the smaller implants.
