I am 5'4" about 116# size 2 with natural 34DD's. EVERYBODY thinks I have fake boobs. That is the insulting part for me. I should be glad about that I suppose because my boobs are still very firm and perky, especially for a 46 yr old who passes for 32. Do I draw attention, YES.
When I married almost 20 yrs ago I was a 34B. When I was pregnant in 1994 I immediately jumped to a DD and did not show in my pregnacy til about 6 months. After baby, I dropped back to a C. I will say I loved the DD's while pregnant. In 2001, I had a hysterectomy and over a couple of years, jumped back to DD. My Dr. thinks it is my hormone. In any case, I love having PERKY DD's. I have no sagging issue nor did anyone in my family. We have very dense breast tissue.
I LOVE my boobs, I enjoy the attention. Hubby loves them. We still have date night weekly. Sure, sometimes someone might speak with me due to boobs, you can tell, the eyes are not looking at your eyes!! Sometimes I do have unwanted attention. Most of the negative attention comes from other women. Isn't that sad? I love and enjoy my boobs and would not trade my experience for another.
As for shirts, yes, I have a little bit of hard time finding clothes to fit. I wear a lot of short skirts or shorts and put a top with it. I buy a larger sized top. I will often have things tailored for me if it is something I really like. I am picky about my clothing because I want to flatter my tiny waist and these new tops that are out this year flatter the boobs (great) but the little flare makes you look pregnant. (Don't want that) I wear a lot of fitted nice tees and tanks. Nordstrom, Guess, GAP body, etc. I am not considered a conservative dresser. My mother still cringes at my clothing choices, but then, she cringes at everything. That is why I live a plane ticket away.
My back, no issue. I wear a Victoria's Secret unlined Body by Victoria bra. I do change out to new bras often. You can tell when they need to be replaced. I do walk a lot, eat in moderation and drink a LOT of water.
Another peeve is all the padding put in some dresses and swimsuits. With DD you don't need that so I always removing that from my clothes before I wear them.
Good luck with your surgery, I hope it goes well and you are pleased with your choice.
