If you want them, go for it!
However the grass isn't always greener on the other side. I had a D cup at age 11. OMG does my size ever hinder my choices at times. From clothing to activities, they get in the way! They are head south much, much sooner. I can't walk around without a bra (and let's admit it, sometimes that is just so comfortable) bc within 15 minutes it feels like they are going to stretch off of my body. Bad visual, I know. I have a hard time buying fitted tops, especially button down because the shirts either pucker or just won't button up and I have to go up 1-2 sizes and then I look like I'm wearing a tent in the waistline. When I dress up, boobs are fun, but going out for business dinners with hubby is very difficult. Anything that isn't layered just right shows too much even when that's the intent; it just happens as the night progresses as clothing settles and shifts. I can't lay on my stomach and now that I'm pregnant I have to special order my bras because I can't find my current size in stores. I have to buy plus sized bras even though I don't shop in the plus size departments. That and they get in the way. I'm constantly spilling stuff on my chest, getting boob-marks in the cake while frosting it (yes, that does happen- a nice boob print for display), and I haven't seen my feet since I was 9. And let's not even talk about bra underwires, bc you have to have them with amplage. They constantly break in half or pop out of them not to mention are constantly riding up into my armpit depsite umph-teen "proper" fittings.
If you get them, just don't go overly enlarged. It's a pain in the tukas.
