Are my breasts saggy? I'm 18 year old girl with bra size 34D. (photo)

Thank you for your question.There is some sagginess of your breasts. In my opinion neither your age nor the extent of sagginess warrants surgery at this time. A non surgical treatment like Thermi Tight may be helpful. Please contact an experienced Board Certified Plastic Surgeon who can help you. All The Best !

Hello dear!!
Thanks you for your question. It is my pleasure to help you with your concerns.
You can be your own best version, and you can definitely achieve amazing results with plastic surgery in order to improve your breasts. For you, I recommend an anchor incision breast lift with areola reduction, for perkier, youthful breasts. No implants are needed. 
I suggest you to make an appointment with a board certified plastic surgeon for a good evaluation and to talk about your goals.
I hope this is helpful.  Good luck :)
